title: Efficient synthesis of (+)-MK7607 and its C-1 epimer via the stereoselective transposition of a tertiary allylic alcohol.
abstract: These studies provide an efficient and stereoselective synthetic route to (+)-MK7607 and its C-1 epimer from a common intermediate in high overall yields. The synthetic methodologies mainly rely on the stereospecific 1,3-allylic transposition of the hindered tertiary alcohol group through a palladium-catalyzed allylic rearrangement as well as a PBr(3)-mediated allylic-transposed bromination.
