Abstract
The cyclic sulphinylation of 2-arylated N-alkoxy-2-vinylglycolamides 1 a-g leads to 3-arylated 1-alkoxy-3-pyrrolin-2-ones 2a-g via the short- lived 1,2,3-oxathiazolidin-4-one 2-oxides 4 in good yields. The synthe sis of the 3-methylated 1-benzyloxy-e-pyrrolin-2-one 2h could be accom plished by thermolytic extrusion of sulfur dioxide from 4h.
