Organomagnesium chemistry plays a crusial role in the stereoselective construction of the two tri-substituted alkenes in the diol (3)-a key intermediate in a synthesis of the spasmogenic diterpenoid zoapatanol (1).A Ni(0)-catalysed coupling of MeMgBr with a dihydrofuran gives the C(6)-C(7) alkene; carbomagnesiation or hydromagnesiation of acetylene intermediates gives the C(2)-C(3) alkene.
