The formation of silylated β-lactams from silylketenes through Lewis acid promoted [2+2] cycloaddition: A combined theoretical and experimental study

The stereoselective formation of silylated cis-β-lactams from (trimethylsilyl)ketene and an α-imino ester by Lewis acid catalysis is described. Theoretical results suggest that the reaction between (trimethylsilyl)ketene and trans- (methoxycarbonyl)-N-methylformaldimine would proceed most favourably with the BF3 catalyst coordinated to the ketene. Moreover, the calculated energy barriers account for the cis:trans ratio found experimentally. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005).
