Diels-Alder Reactions of 2- and 3-Vinyl-1-(phenylsulfonyl)pyrroles
Xiao, Dong,Ketcha, Daniel M.
, p. 499 - 504 (2007/10/02)
Regioselectively produced 2- and 3-acetyl-1-(phenylsulfonyl)pyrroles can be reduced to the corresponding alcohols and subsequently dehydrated to afford N-protected vinylpyrroles.These remarkably stable vinylpyrroles can then serve as heterodienes in 4 +
