Article abstract of DOI:10.1016/S0040-4020(98)00930-2

Arenesulfonamides, sulfamide, and cyanamide are efficiently allylated using allylic carbonates under Pd(0)-catalysis. N-Arenesulfonyl-2,5- dihydropyrroles are obtained by ruthenium-mediated ring closing metathesis of the corresponding N-diallylated compounds. A stereochemical study of the reactions of ethyl cis-(5-methyl-2-cyclohexenyl) carbonate with 2,4,6- triisopropylphenylsulfonamide was performed, clean overall retention of configuration being found with bidentate phosphines.
