Le Barbu-Debus, Katia; Zehnacker, Anne published their research in Chirality in 2021. The article was titled 《Competition between inter and intramolecular hydrogen bond evidenced by vibrational circular dichroism spectroscopy: The case of (1S,2R)-(-)-cis-1-amino-2-indanol》.Safety of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol The article contains the following contents:
The IR (IR) absorption and vibrational CD (VCD) spectra of an intramolecularly hydrogen-bonded chiral amino-alc., (1S,2R)-(-)-cis-1-amino-2-indanol, are studied in DMSO-d6. The spectra are simulated at the d. functional theory (DFT) level within the frame of the cluster-in-the-liquid model. Both IR and VCD spectra show a clear signature of the formation of intermol. hydrogen bonds at the detriment of the intramol. OH …N interaction present in the isolated mol. Two solvent mols. are necessary to reproduce the exptl. spectra. Whereas the first DMSO mol. captures the main spectral modifications due to hydrogen bond formation between the solute and the solvent, the second DMSO mol. is necessary for a good description of the Boltzmann contribution of the different complexes, based on their Gibbs free energy.(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Safety of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol) was used in this study.
(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Primary amines having a tertiary alkyl group (R3CNH2) are difficult to prepare with most methods but are made industrially by the Ritter reaction. In this method a tertiary alcohol reacts with hydrogen cyanide (HCN) in the presence of a concentrated strong acid; a formamide, RNH―CHO, is formed first, which then undergoes hydrolysis.Safety of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol
