The tin(II) enolate is generated from 3-acylthiazolidine-2-thione with β-alkoxy or β-amino functionality on treatment with stannous triflate in the presence of N-ethylpiperidine.The enolate further reacts with aldehyde to afford the aldol product with high syn-stereoselectivity.The aldol product thus produced is stereospecifically converted to β-lactam derivative with hydroxyethyl side chain.

Several ?-allyltricarbonyliron (lactone) complexes have been treated with an excess of benzylamine in the presence of Lewis acids to afford the corresponding lactam complexes by SN2'-like process.These lactam complexes were oxidised in good yie
