| abstract |
N-(3-Carboxyphenylacetyl)-L-cysteinyl-D-valine and N-(3--carboxyphenylacetyl)-L-cysteinyl-D-modified-valine dipeptides are substrates for isopenicillin N synthetase conversion to penams e.g. 2-vinyl-2-methylpenam, 2-allenylpenam and 2-methoxypenam. The substitution of the 3-carboxyphenylacetyl group for the 2-a-aminoadipoyl group of the natural tripeptide L-AAA-L-cys-D-val and tripeptides with modified valine affords efficient conversion to the penams. |
