PROCESS FOR CONVERTING α-ACYL-SUBSTITUTED LACTONES TO α-ALKYLIDENE-SUBSTITUTED LACTONES |
| abstract |
A convenient stereoselective process for the preparation of α-alkylidene-substituted-η-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. |
