Oxidative cyclization of gamma-alkylidene butenolides. Stereoselective preparation of spirolactones
Arkivoc（2012）
Abstract
A new route to 1,6-dioxaspiro[4.4]non-3-en-2-ones is established by bromoetherification of dihydroxybutenolides. An asymmetric total synthesis of 8-epi-crassalactone D starting from methyl cinnamate has been accomplished.
