A Versatile Route to (E)- and (Z)-2-Hydroxy-3,4-unsaturated Disubstituted Sulfilimines and Their Haloamidation Reaction
摘要:
alpha-Chloro ynones have been reduced using Noyori's Ru catalyst to furnish alpha-chloro propargylic alcohols with excellent enantioselectivity. These have been used as a common precursor for the preparation of (E)- and (Z)-2-hydroxy-3,4-unsaturated disubstituted sullfilimines. The latter serve as precursors for the highly regio- and stereoselective preparation of bromo carbamates.
