The Staudingersynthesis of various β-carbolines and thienopyridines with acetyl chloride derivatives led to novel β-lactam-type fused heterocyclic compounds. The reaction was stereospecific, giving exclusively the cis cycloadducts as racemates. The enthalpy profile and the driving force for the cis-selectivity of this cycloaddition was studied by high level quantum chemical calculations and was assigned
