Regiodivergent Addition of Phenols to Allylic Oxides: Control of 1,2‐ and 1,4‐Additions for Cyclitol Synthesis

Abstract Control of 1,2‐ and 1,4‐addition of substituted phenols to allylic oxides is achieved by intercepting palladium π‐allyl complexes. The interconversion of palladium complexes results in the total synthesis of MK 7607, cyathiformine B type, streptol, and a new cyclitol.
