Dianion of a-mercapto-?-butyrolactone was successfully generated by treating a-mercapto-?-butyrolactone with lithium diisopropylamide-N,N,N',N'-tetramethylethylenediamine at -78°C in THF. This dianion was found to be highly reactive toward electrophilic reagents. A new methodology for the stereoselective synthesis of a-alkylidene-?-butyrolactones by one-pot procedure has been developed. |
