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 products are precursors of α-aminolactone as pure diastereomers.

Abstract
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 products are precursors of α-aminolactone as pure diastereomers.File in questo prodotto:
