Dihydropyridin-2-imines were synthesized and biologically evaluated both in vitro and in vivo using a nitric oxide inhibition assay. Compounds 1, 4, 5 and 7-11 exhibited potent activity in the inducible nitric oxide (iNOS) inhibition assay. Of these 5, 6,

A number of 6-substituted 7-oxo-1-azabicyclohept-2-ene-2-carboxylates related to the olivanic acids were prepared from the phosphorane (32).Generation of the anion α to the azetidin-2-one carbonyl group, followed by reaction with electrophiles and intramolecular cyclisation using the Wittig procedure gave the bicyclic products; in all cases the thermodynamically favoured trans-stereochemisty about the azetidinone ring predominated.In contrast, some less readily available cis-substituted analogues were obtained from the cyclohexa-1,4-diene derived phosphorane (61).The synthetic utility of a masked acetonyl ester group for preparing the free acids of these azabicycloheptene ring systems is described.
