Benzyl 6α-acetoxypenicillanate was transformed into benzyl 6α-hydroxypenicillanate by enzymatic cleavage of the acetyl group. The preparation of several side chain oxygen analogues of the penicillins is described.
AbstractThe synthesis of 6α‐acyloxy‐penicillanic acids either by deamination of 6‐amino‐penicillanic acid or by rearrangement of N‐nitroso‐penicillins is described.
