2-Dialkylimidazoles can be converted to nucleophilic 2-alkylidene imidazolines upon treatment with (BOC)2O under mild conditions. Incorporation of a β-keto amide carbonyl electrophile in the 2-alkylimidazole side chain results in intramolecular aldol-like cyclization to afford imidazole-functionalized γ-lactams. Positioning of a ketone electrophile in a 1-alkyl side chain results in cyclization at the 2-position to afford

Compounds of the formula:
wherein
R is alkyl of 1 to 12 carbon atoms, cyclopentyl, cyclohexyl, cyclopentylloweralkyl or cyclohexylloweralkyl;
Z is ethylene or propylene, optionally substituted with a single substituent which is lower alkyl;
A is the integer 1, 2, or 3; and the pharmaceutically acceptable acid addition salts thereof, said compounds being useful as spermicidal, antimicrobial and anticonvulsant agents and thromboxane synthetase inhibitors.
