Zj. Witczak et al., THIOSUGARS .2. A NOVEL-APPROACH TO THIODISACCHARIDES - THE SYNTHESIS OF 3-DEOXY-4-THIOCELLOBIOSE FROM LEVOGLUCOSENONE, Carbohydrate research, 301(3-4), 1997, pp. 167-175
An expeditious methodology for the synthesis of beta-(1 --> 4)-3-deoxy
thiodisaccharides (3-deoxythiocellobiose) has been developed. The meth
odology is based on the stereoselective Michael addition of 2,3,4,6-te
tra-O-acetyl-1-thio-beta-D-glucose to levoglucosenone, followed by ste
reoselective reduction at C-2 with L-Selectride(R) and DIBAH, followed
by acetolysis to the target thiodisaccharide derivative. (C) 1997 Els
