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
Process for converting α-acyl-substituted lactones to α-alkylidene-substituted lactones
-
, (2008/06/13)
A convenient stereoselective process for the preparation of α-alkylidene-substituted-γ-butyrolactones and δ-valerolactones is provided. The process involves reacting an α-acyl lactone, an aldehyde, and an alkali metal hydroxide in an inert diluent at an elevated temperature while removing water.
