Synthesis of Monocyclic β-Lactams with a Terpenoid Moiety
Varma, R. Luxmi,Narayanan, C. S.
, p. 302 - 304 (2007/10/02)
A series of new monocyclic β-lactams with a terpenoid moiety have been prepared by reaction of schiff bases with appropriate terpenyl acid chlorides in the presence of triethylamine.Their structural assignments are based on elemental analyses and spectral
