A new, solvent-free, vapour-assisted method, developed for the synthesis of carbocyclic cis beta-amino acid enantiomers through the Candida antarctica lipase B-catalysed enantioselective (E >200) hydrolysis of beta-lactams with 0.5 equiv of H2O at 70 degrees C, has been demonstrated to be applicable on a preparative scale to produce (+/-)-2 (the starting racemate for cispentacin), (+/-)-3 (the starting racemate for 4-tert-butylcispentacin, a new cispentacin analogue) and (+/-)-7 (the starting racemate for 1,4-ethylene-bridged cispentacin).
