Abstract Part I: A first reported method for preparation of a new class of acrylamide thioglycosides via one-pot reaction of the potassium 2-cyanoethylene-1-thiolate salts with 2,3,4,6- tetra-O-acetyl-a-D-gluco- and galactopyranosyl bromides has been studied. The E-configuration of these thioglycosides were proven by their transformations to the corresponding 5-aminopyrazoles. Part II: A first reported method for preparation of a new class of thiophene thioglycosides via one-pot reaction of the sodium thiophenethiolate salts with 2,3,4,6-tetra-O-acetyl-a- D-gluco- and galactopyranosyl bromides has been studied. The sodium thiophenethiolate salts are prepared using sodium cyanoethylene thiolate salts. |
