Ring-Closing Metathesis Reactions of Acyloxysulfones: Synthesis of γ-Alkylidene Butenolides

An acyloxysulfone ring-closing metathesis/sulfone elimination sequence has been developed for the preparation of various γ-alkylidene butenolides. The elimination is proposed to proceed via an E1cb mechanism leading to (Z)-γ-alkylidene butenolides as the major products.

Synthesis and stereochemical assignments for goniobutenolides A and B

Goniobutenolides A and B and their C-7 epimers are stereoselectively synthesized using osmium-catalyzed asymmetric dihydroxylation (AD) as the key transformation. The relative and absolute stereochemistry of the natural goniobutenolides A and B are assigned with reference to the spectral data and optical rotations from the literature.
