[摘要]An efficient cross-coupling reaction of N-allylic sulfonimides with organozinc reagents has been developed. In the presence of 1 mol-% of Pd2(dba)3, a range of N-allylic sulfonimides smoothly couple with various organozinc reagents at room temperature to give the corresponding (E)-alkene products in moderate to excellent yields and with good to exclusive a-selectivity. It is noteworthy that allyl ether, benzyl ether, and ester are tolerated under the reaction conditions.
