Regiospecific Baeyer-Villiger Oxidation of α,α-Dichlorocyclobutanones: A Norbisabolide γ-lactone Analogue1
摘要:
Details and methodological comparisons are presented on the preparation of a norbisabolide gamma-lactone analogue (4) via dichloroketene cycloaddition to limonene followed by regioselective Baeyer-Villiger oxidation (CH3CO3H) of the alpha,alpha-dichlorocyclobutanones 3 and C-Cl reduction (Zn/HOAc). The sequence of reduction followed by oxidation (HOCl) applied to 3 produced 4 in much better yield.

to an unusual carbon skeleton rearrangement. The carbonyl group of carvone enhances the reactivity of the radical cyclization, changes the ring-opening pathway and leads to the formation of a new tricyclic dione product.
