Abstract
Enantiopure N,N-disubstituted amides are obtained in good yield from ( -)-2,2-dimethyl-3-formylcyclopropane-1-carboxylic acid in three steps: dithiane protection of the aldehyde function; amidation of the carbox ylic acid function; dethioketalization. Mono-N-substituted amides rear range to a bicyclic lactam form. The X-ray structure of a dithiane-pro tected mono-N-substituted amide intermediate is reported.
