A short and common stereoselective approach to 5/6, 6/6, 6/7 bicyclic aza sugars
摘要:
An efficient and highly stereoselective approach to bicyclic aza sugars is described using Grignard reaction on an N-benzyl imine derived from 3-O-benzyl-1,2-O-isopropylidine-alpha-D-xylo-pentodialdofuranose, ring closing metathesis, and reductive cyclization as key steps.
