Abstract
2-Methyleneazetidines have been synthesized and isolated by the reaction of beta-lactams with dimethyltitanocene, followed by chromatography on deacti vated silica. Efficient conversion required that the lactam nitrogen be str ongly deactivated. Methyl transfer predominated in reactions with phenyl an d benzyl on the lactam nitrogen.
