Utilization of sugars in organic synthesis: Utilization of sugars in organic synthesis. Part XII. On the possibility of direct O-1b ? O-6 acyl migration in 1-O-acyl-b-D-glucose derivatives. Yoshimoto, Kimihiro; Tsuda, Yoshisuke (Fac. Pharm. Sci., Kanazawa Univ., Kanazawa 920, Japan). Chem. Pharm. Bull., 31(12), 4335-40 (English) 1983. CODEN: CPBTAL. ISSN: 0009-2363. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Section cross-reference(s): 22 In order to clarify whether or not direct O-1b ? O-6 acyl migration in O-acyl-D-glucose derivs. really occurs, 3-O-methyl-1-O-myristoyl-b-D-glucopyranose and 3-deoxy-1-O-myristoyl-b-D-glucopyranose were synthesized and their acyl migration was examd. 4613-62-1 and 5149-37-1 which are cas registry numbers of chemicals are mentioned. under thermal, solvolytic, and base- and acid-catalyzed conditions. Neither compd. showed any tendency for any migration under these conditions (only partial solvolysis was obsd. under solvolytic conditions). Therefore O-1b ? O-6 acyl migration does not occur directly, but proceeds through the path O-1b ? O-3 ? O-6. .
