Abstract
The preparation of 3-alkyl-4-(chloromethyl)-1-RSO2-1H-pyrrol-2(5H)-ones was efficiently accomplished through a[1,2]-elimination of g-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.
