A Annulation Approach to Nitrogen Heterocycles Using 2,3-Bis(phenylsulfonyl)-1,3-butadiene and Primary Amines

The reaction of amines with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords pyrrolidines in high yield.The formation of nitrogen heterocycle involves initial conjugate addition and this is followed by a 5-endo-trig cyclization of the resulting amine onto th

SYNTHESIS OF 3-PYRROLINES VIA A -ANNULATION STRATEGY

The reaction of amines with 2,3-diphenylsulfonyl-1,3-butadiene produces 3-pyrrolines which are readily oxidized to 3-phenylsulfonyl pyrroles.
