Abstract

The preparation of 3-alkyl-4-(chloromethyl)-1-RSO₂-1H-pyrrol-2(5H)-ones was efficiently accomplished through a [1,2]-elimination of γ-lactams derived from the copper(I)-catalysed ATRC of 2,2-dichloro-N-(2-chloroallyl)-N-RSO₂-amides. The two reactions can be integrated into a sequential one-pot process.

Key words

copper - cyclization - elimination - lactams - radical reaction
