4-Substituted α-ylidene-γ-butyrolactones produce N-ethoxycarbonyl-spiroaziridino γ-lactone diastereomers on treatment with NsONHCO2Et and CaO. A good stereofacial preference is observed when the ring substituent is a phenyl group. These product

A facile method for highly stereoselective synthesis of α-arylidene (4a-d, 4f-h and 4j) and α-ethylidene (4e,4i)-γ-butyrolactones has been developed by acid catalyzed lactonization of the corresponding α-ylidene-γ,δ-unsaturated esters 3a-j.The required es
