Iridium-catalyzed enantioselective allylation of sodium 2-aminobenzenethiolate: an access to chiral benzo-fused N,S-heterocycles

The use of sodium 2-aminobenzenethiolate in the enantioselective iridium catalyzed allylic substitution with a range of methyl allyl carbonates allows the concise synthesis of the branch-type products with both excellent regio- and enantioselectivities, which are functionalized N,S-containing allylic intermediates for the formation of chiral benzo-fused N,S-heterocycles.
