The Preparation of Fused Ring α, β-Unsaturated Lactones using Lithium Ethoxyacetylide. Syntheses of Dihydroactinidiolide and Actinidiolide, and Partial Synthesis of Dihydrosecurinine

Abstract

The syntheses of (±) -dihydroactinidiolide and (±) -actinidiolide, and partial synthesis of dihydrosecurinine were described. Lithium ethoxyacetylide procedure was shown to be a useful method for the preparation of fused ring α, β-unsaturated lactones.
