In 2010,Angewandte Chemie, International Edition included an article by Liu, Taifeng; Liu, Yan; Xuan, Weimin; Cui, Yong. Application In Synthesis of (R)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol. The article was titled 《Chiral nanoscale metal-organic tetrahedral cages: diastereoselective self-assembly and enantioselective separation》. The information in the text is summarized as follows:

Chiral atropisomeric 1,1′-biphenyl-3,3-diyl-bridged 1,3-diketones and their iron(III) and gallium complexes undergo self-assembly yielding tetrahedral homochiral clusters possessing chiral cavity; alcs. were resolved by formation of host-guest compounds with the iron(III) cluster tris-diketonate. Diacetylation of (1S)- and (1R)-5,5′,6,6′-tetramethyl-2,2′-(OMOM)2-1,1′-biphenyl-3,3′-dicarboxaldehyde [3,3′-Q(CHO)2] by biacetyl-trimethyl phosphite complex gave the enantiopure bis-diketonate proligands, 3,3′-Q[CH(COMe)2]2. These ligands were reacted with FeCl3 and GaCl3 giving the corresponding tetrameric nanoscale complex hosts, [Fe[3,3′-Q[C(COMe)2]2]3]4 (1) and [Ga[3,3′-Q[C(COMe)2]2]3]4 (2), composed from homochiral ΔΔΔΔ- or ΛΛΛΛ-units, for ligands (1R)- and (1S)-3,3′-Q[CH(COMe)2]2, resp. Inclusion of racemic 2-butanol and 3-methyl-2-butanol into chiral cavity of (1S)-1 with subsequent desorption gave the corresponding resolved alcs. with >99% ee.

The article was titled 《Nickel-catalyzed, regio- and enantioselective benzylic alkenylation of olefins with alkenyl bromide》, and you may find the article in Angewandte Chemie, International Edition.Computed Properties of C12H20O6 The information in the text is summarized as follows:

A NiH-catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using a chiral bisoxazoline ligand.((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6Computed Properties of C12H20O6) was used in this study.

Sashidhara, Koneni V.; Rao, K. Bhaskara; Kushwaha, Pragati; Modukuri, Ram K.; Singh, Pratiksha; Soni, Isha; Shukla, P. K.; Chopra, Sidharth; Pasupuleti, Mukesh published an article in ACS Medicinal Chemistry Letters. The title of the article was 《Novel Chalcone-Thiazole Hybrids as Potent Inhibitors of Drug Resistant Staphylococcus aureus》.Electric Literature of C12H14O3 The author mentioned the following in the article:

A series of novel hybrids I [R = t-Bu, iso-Pr, n-propyl; R1 = 4-Me-C6H4, 4-MeO-C6H4, furan-2-yl, thiophene-2-yl; R2 = CO2Et, 4-MeO-C6H4, 3,4-dimethoxyphenyl.] possessing chalcone and thiazole moieties were synthesized and evaluated for their antibacterial activities. In general this class of hybrids exhibited potency against Staphylococcus aureus, and in particular, compound I [R = t-Bu, R1 = 4-Me-C6H4, R2 = 3,4-dimethoxyphenyl.] exhibited potent inhibitory activity with respect to other synthesized hybrids. Furthermore, the hemolytic and toxicity data demonstrated that the compound I [R = t-Bu, R1 = 4-Me-C6H4, R2 = 3,4-dimethoxyphenyl.] was nonhemolytic and nontoxic to mammalian cells. The in vivo studies utilizing a S. aureus septicemia model demonstrated that compound I [R = t-Bu, R1 = 4-Me-C6H4, R2 = 3,4-dimethoxyphenyl.] was as potent as vancomycin. The results of antibacterial activities underscore the potential of this scaffold that can be utilized for developing a new class of novel antibiotics.

The author of 《A Short and Convenient Synthesis of closo-Dodecaborate Sugar Conjugates》 were Imperio, Daniela; Muz, Barbara; Azab, Abdel Kareem; Fallarini, Silvia; Lombardi, Grazia; Panza, Luigi. And the article was published in European Journal of Organic Chemistry in 2019. Synthetic Route of C12H20O6 The author mentioned the following in the article:

Dodecaborate anions represent a suitable boron source for boron neutron capture therapy (BNCT). Sugar derivatives of dodecaborate have been prepared through the ring-opening reaction of cyclic oxonium ions by alkoxide nucleophiles. According to this general approach, a convenient and short synthesis of three derivatives of dodecaborate-sugar conjugates is herein reported. Glucose, galactose and fructose have been chosen for their expected preferential uptake by tumor cells compared to healthy cells. The free hydroxyl group of isopropylidene protected sugars was exploited as nucleophile to open a dodecaborate cyclic oxonium salt, giving products containing a spacer between the sugar and the boron cluster. Deprotection of the sugar moiety in acidic conditions gave the desired compounds in excellent yield.((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6Synthetic Route of C12H20O6) was used in this study.

In 2019,International Journal of Hydrogen Energy included an article by Ding, San-Yuan; Wang, Peng-Lai; Yin, Guan-Lin; Zhang, Xuqiang; Lu, Gongxuan. Synthetic Route of C9H6O6. The article was titled 《Energy transfer in covalent organic frameworks for visible-light-induced hydrogen evolution》. The information in the text is summarized as follows:

We report herein the use of covalent organic frameworks (COFs) to facilitate the energy transfer from sensitizer to the active sites for efficient photocatalysis. The results indicate that the photocatalytic efficiency can be apparently enhanced by using the layered COFs. The visible-light-induced hydrogen evolution rate (10.4 mmol g-1 h-1) for Pd0/TpPa-1 sensitized by Eosin Y was 10 times higher than that of Pd/C. The enhanced photocatalytic H2-production activity could be originated from the improvement of the photogenerated electron transfer in conjugated COFs. The important role of COFs in facilitating the transfer of photogenerated electrons was verified by the transient photocurrent response and the luminescence anal. This research highlights the use of COFs to investigate the energy transfer process. In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Synthetic Route of C9H6O6) was used in this study.

The author of 《Hierarchical-Coassembly-Enabled 3D-Printing of Homogeneous and Heterogeneous Covalent Organic Frameworks》 were Zhang, Mingshi; Li, Longyu; Lin, Qianming; Tang, Miao; Wu, Yuyang; Ke, Chenfeng. And the article was published in Journal of the American Chemical Society in 2019. Formula: C9H6O6 The author mentioned the following in the article:

Covalent organic frameworks (COFs) are crystalline polymers with permanent porosity. They are usually synthesized as micrometer-sized powders or two-dimensional thin films and membranes for applications in mol. storage, separation, and catalysis. In this work, we report a general method to integrate COFs with imine or β-ketoenamine linkages into three-dimensional (3D)-printing materials. A 3D-printing template, Pluronic F127, was introduced to coassemble with imine polymers in an aqueous environment. By limitation of the degree of imine polycondensation during COF formation, the amorphous imine polymer and F127 form coassembled 3D-printable hydrogels with suitable shear thinning and rapid self-healing properties. After the removal of F127 followed by an amorphous-to-crystalline transformation, three β-ketoenamine- and imine-based COFs were fabricated into 3D monoliths possessing high crystallinity, hierarchical pores with high surface areas, good structural integrity, and robust mech. stability. Moreover, when multiple COF precursor inks were employed for 3D printing, heterogeneous dual-component COF monoliths were fabricated with high spatial precision. This method not only enables the development of COFs with sophisticated 3D macrostructure but also facilitates the heterogeneous integration of COFs into devices with interconnected interfaces at the mol. level. The experimental part of the paper was very detailed, including the reaction process of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Formula: C9H6O6)
