Stereoselective synthesis of novel 4'-branched and bicyclo(3.1.0)hexane-templated nucleoside.

摘要

The racemic and stereoselective synthesis of a novel nucleoside 4'-branched and bicyclo[3.1.0]hexane templated nucleoside 15 was accomplished using a [3,3]-sigmatropic rearrangement, an intramolecular carbene cycloaddition reaction and a Curtius rearrangement as the key reactions.
