Stereoselective Synthesis of(Z)-4-(2-Bromovinyl)benzenesulfonyl Azide and Its Synthetic Utility for the Transformation to(2)-N-4-(2-Bromovinyl)benzenesulfonylimidates
A novel method for the stereoselective synthesis of(Z)-4-(2-bromovinyl)benzenesulfonyl azide by simultaneous azidation and debrorninative 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-bromovinyi)benzenesulfonyl azide,terminal alkynes and alcohols/phenols.
