An improved method for the preparation of some ethyl 1-thioglycosides

An improved method for the preparation of some ethyl 1-thioglycosides. Das, Saibal Kumar; Roy, Nirmolendu (Dep. biological Chem., Indian Assoc. Cultivation Science, Calcutta 700 032, India). Carbohydrate Research, 296, 275-277 (English) 1996 Elsevier. CODEN: CRBRAT. ISSN: 0008-6215. 79389-52-9 and 4163-65-9 are also in the experiment. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Et 1-thioglycosides were prepd. in almost quant. yield from sugar peracetates in 3:2 chloroform-ether, with boron trifluoride di-Et etherate as catalyst. D-Galactose, D-glucose, and 2-deoxy-2-phthalimido-D-glucose yielded almost exclusively b anomers, whereas L-rhamnose and D-mannose resulted predominantly in the a anomers. .
