Abstract
A novel method for the stereoselective synthesis of (Z)-4-(2-bromovinyl)benzenesulfonyl azide by simultaneous azidation and debrominative decarboxylation of anti-2,3-dibromo-3-(4-chlorosulfonylphenyl)propanoic acid using NaN3 only was developed. Facile transformation of (Z)-4-(2-bromovinyl)benzenesulfonyl azide to (Z)-N-[4- (2-bromovinyl)benzenesulfonyl]imidates was also achieved by Cu-catalyzed three-component coulping of (Z)-4-(2-bromovinyl)benzenesulfonyl azide, terminal alkynes and alcohols/phenols.
