A new approach to isolevoglucosenone via the 2,3-sigmatropic rearrangement of an allylic selenide
Witczak, Zbigniew J.,Kaplon, Peter,Kolodziej, Mark
, p. 143 - 148 (2002)
A convenient method is described for the synthesis of isolevoglucosenone 5, via allylic selenide 3, and its rearrangement to allylic alcohol 4, followed by oxidation with manganese oxide. Isolevoglucosenone 5, is produced in 62% overall yield.
