Formation of Polysubstituted 1,2,5,6-Tetrahydropyridines from the 4 + 2 Cycloaddition Reaction of Bis(phenylsulfonyl)butadienes with Aryl Imines

The reaction of 2,3-bis(phenylsulfonyl)-1,3-bitadiene with aryl imines affords N-alkyl-3,5-bis(phenylsulfonyl)-1,2,5,6-tetrahydropyridines in high yield.The formation of the rearranged cycloadducts proceeds by a mechanism that involves addition of benzene

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

2,3-DI(PHENYLSULFINYL)-1,3-BUTADIENE VIA A DOUBLE -SIGMATROPIC REARRANGEMENT OF THE BIS-SULFENATE ESTER OF 2-BUTYNE-1,4-DIOL.

A one-step conversion of butyne-1,4-diol (1) to 2,3-di(phenylsulfinyl)-1,3-butadiene (4) and the conversion of this bis-sulfoxide to the sulfoxide-sulfone 6 and the bis-sulfone 5 are reported.
