A newseries of 6-(hydroxyethyl)penems 2-substituted with amino acid-related sidechains was synthesized. The nature of the amino acyl derivative proved to be crucial both from a synthetic point of view, as beta-lactam ring opening can compete with C-2 nucleophilic substitution, and for antibacterial activity. Primary amino acid amides emerged as the most suitable sidechains for enhancing permeability

Synthesis of cis-3-hydroxy-l-proline fromd-glucose is reported. The methodology involves conversion of d-glucose into N-benzyloxycarbonyl-γ-alkenyl amine which on 5-endo-trig-aminomercuration gave the pyrrolidine ring skeleton with sugar appendage in 25% yield. Alternatively, N-benzyloxycarbonyl-γ-alkenyl amine on hydroboration–oxidation, mesylation and intramolecular SN2 cyclisation afforded pyrrolidine
