摘要: 6β-(L-α-Aminoadipoyl)-2α-vinyl-2β-methylpenam-3-carboxylic acid is provided in an enzymatic process converting δ-(L-α-aminoadipoyl)-L-cysteinyl-D-γ,δ-didehydroisoleucine with isopenicillin N synthetase. The 2α-vinylpenam product is converted by known methods to the 6β-amino-2α-vinyl-2β-methylpenam-3-carboxylic acid nucleus and the latter is N-acylated to provide corresponding 6β-acylaminopenams.
