The reaction of alpha- and beta -1-S-phosphorothioates of per-O-acetylated monosaccharides (galactose, xylose, glucose) with trimethylsilyl cyanide in the presence of boron trifluoride etherate has been investigated. It has been established that in dichloromethane 1,2-O-cyanoethylidene derivatives of aldoses are formed in high yields. When the reaction was carried out in acetonitrile, peracetylated galactosyl cyanide was formed as the major product. (C) 2000 Elsevier Science Ltd. All rights reserved.
