Asymmetric synthesis of α-methylene-γ-butyrolactones fused to carbocyclic rings via the Hosomi reaction of chiral allylsilanes
Optically active α-methylene-γ-butyrolactones fused to five or six-membered carbocyclic ring were synthesized in 64-92% enantiomeric excess using the intramolecular Hosomi reaction of ω-formylated β-(chiral)alkoxycarbonylallylsilanes.
