Based on insight gleaned from our previous work on Pdcatalyzed carbonyl dehydrogenation, 32 we anticipated that stannane 6-1 could be accessed by direct conversion of an abundantly available enone precursor, 6-methylcyclohexenone (5-2) 28 through a bimetallic enolate intermediate 6-4 (Scheme 6C). This approach would require a selective transmetallation of an allyl palladium species 6-3 with the metal enolate, rather than transmetallation with the allyl-stannane, to form a palladium enolate that could regenerate the enone functionality via β-hydride elimination.
