Addition of Organozinc Reagents to Glycopyranosyl Cyanides: Access to Keto Ester- C -glycosides or Unsaturated Acyl- C -glycosides
Résumé
Addition of Reformatsky-type or allylic zinc reagents to 2,3,4,6-tetra-O-benzylglycopyranosyl cyanides led to keto ester-C-glycosides or unsaturated acyl-C-glycosides in moderate to excellent yields in the galactose, glucose, and mannose series.
