6-(.alpha.-3-Acyl-unreidoacetamido)-penicillanic acids and pharmaceutically acceptable non-toxic salts thereof in which the hydrogen atom of the nitrogen atom present in the 3-position is substituted, are effective against Gram-positive and Gram-negative infections, particularly Klebsiella aerobacter infections.

Abstract Alkyl carbamate (such as 1) reacts with triphosgene at the nitrogen atom, whereas the analogous thionocarbamates (5) react at the sulfur. Subsequent treatment with various phenols or alcohols leads to the corresponding aryl carbamates or alkyl carbamates (6) respectively. The process thus involves both desulfurization and transesterification.
