A variety of 1,7-enynes undergo nucleophilic boration and cyclization with bis(pinacolato)diboron catalyzed by Pd bis(trifluoroacetate), affording alkylidenecyclohexane-substituted homoallylic and allylic boronates by formation of C-C and C-B bonds. Reaction of CR3R4:CR2CH2XYCH2CCR1 [X = C(CO2Me)2, C(SO2Ph)2, Y = CH2; X = CH2, Y = C(CO2Me)2, NTs] with pin2B2, catalyzed by Pd(TFA)2 gave methylenecyclohexanes I (2a–i, 4a–h, R1 = H, Me, Ph, TMS; R2-R4 = H, Me, CH2OAc) together with cyclohexenylmethyl boronates II [5, Y = C(CO2Me)2, NTs]. The reaction mechanism comprises palladium addition to the triple bond with subsequent formation of palladaindene and elimination; the compounds 5 were rationalized as products of palladium-catalyzed isomerization of 4.
