Palladium-catalyzed asymmetric propargylic sulfonylation of propargyl esters with sulfonyl hydrazides.

Palladium-catalyzed enantioselective propargylic sulfonylation between racemic propargyl esters and readily available sulfonyl hydrazides with an N-benzylamino-bridged bidentate phosphoramidite (N-Bn-Me-BIPAM) ligand was reported. The corresponding r…
