Decyanation of 2-Oxoazetidine-4-carbonitriles as a New Route to (4S)-4--azetidin-2-one, an Intermediate for the Synthesis of 1β-Methylcarbapenem Antibiotics
Base-catalysed cyclisation of the α-bromoacetamides derived from aminonitriles gave 4-alkyl- and 4-aryl-2-oxoazetidine-4-carbonitriles in high yield, whose cyano group was removed with sodium in liquid ammonia. (3R)-2-(4-Methoxybenzylamino)-3-benzyloxy-me
