In 2022,Sarkar, Souradip; Samanta, Rajarshi published an article in Organic Letters. The title of the article was 《Weakly Coordinating tert-Amide-Assisted Ru(II)-Catalyzed Synthesis of Azacoumestans via Migratory Insertion of Quinoid Carbene: Application in the Total Synthesis of Isolamellarins》.Related Products of 7748-36-9 The author mentioned the following in the article:
A weakly coordinating tert-amide-directed straightforward method was developed for the synthesis of azacoumestans, e.g., I, using the corresponding azaheterocycle derivatives II (R1 = H, Me, Bn, etc., R2 = H, Me, R3 = Cl, F, R4 = MeO, Br, Ph, etc.) and diazonaphthoquinones III (R5 = OH, R6 = Br, COMe, Ph, etc.) under cheap Ru(II)-catalyzed conditions. The reaction proceeds via migratory insertion of quinoid carbene and subsequent Bronsted acid-mediated cyclization. The optimized C2-selective method offered a wide scope of important azaheterocycles. Bioactive natural products like isolamellarins A and B were synthesized via the developed protocol. Preliminary mechanistic studies highlighted the probable mechanistic pathway. The results came from multiple reactions, including the reaction of Oxetan-3-ol(cas: 7748-36-9Related Products of 7748-36-9)
Oxetan-3-ol(cas: 7748-36-9) is used as a reagent in the synthesis of 5-fluoro-4,6-dialkoxypyrimidine GPR119 agonists. It is also used as a reagent in the synthesis of cyclic sulfone hydroxyethylamines as potent and selective β-site APP-cleaving enzyme 1 (BACE1) inhibitors.Related Products of 7748-36-9
