Polyketide Assembly by Alkene–Alkyne Reductive Cross-Coupling: Spiroketals Through the Union of Homoallylic Alcohols
摘要:
A reaction sequence involving regioselective formal hydroalkynylation, reductive ene-yne cross-coupling, and oxidative cyclization is developed to prepare stereochemically dense spiroketals following similar pathways.
