Alkenylzinc-Mediated Approach to the Vitamin D Skeleton. Application to the Synthesis of 6-Methyl Analogs of Vitamin and Previtamin D

Palladium-catalyzed cross-coupling of alkenylzinc reagents, bearing the C,D-ring/side chain portion, and (Z)-1-iodo-1,3-bis-exocyclic dienes (as A-ring precursors), provides a mild, convergent entry to the vitamin D skeleton, that is suitable for the synt
