Total synthesis of (±)-cinnamolide and (±)-methylenolactocin–an approach to butenolides using S-alkoxycarbonyl xanthates
Abstract
The total synthesis of (±)-cinnamolide 9 and (±)-methylenolactocin 15 is accomplished using as the key step a radical cyclisation involving alkoxycarbonyl radicals derived from S-alkoxycarbonyl xanthates.
