Synthesis of C‐3 Branched Allyl and Pentadienyl Glucosamines via Radical Coupling of Sugar‐Thionocarbonates

Abstract The intermolecular AIBN‐promoted free radical reaction of glucosamine thionocarbonates as radical donors, and allyl or pentadienyl‐tributyltin reagents gave the expected C‐3 branched sugar derivatives in good yield and with total equatorial selectivity.
