  摘要：

  AbstractA palladium(0)‐catalyzed reaction of 2‐allyl‐3‐indolyl boronates/propargylic carbonates was observed to afford dihydrocycloocta[b]indoles highly efficiently via carbon‐carbon coupling, [1,5]‐hydrogen migration involving dearomatization, and electrocyclization involving rearomatization. Their thermal reactions with the addition of dienophiles involving eletrocyclization and [4+2] cycloaddition have been studied.magnified image

  Enantioselective conjunctive cross-coupling with propargylic carbonates affords β-boryl allenes as the reaction product. The reaction is found to proceed through the intermediacy of dimethoxyboronate complexes that are generated in situ by a strain-induced ligand exchange reaction.

  An efficient and highly regioselective route to synthesize polysubstituted 1,3,4-alkatrien-2-yl cyclopropane derivatives via Pd(0)-catalyzed highly regioselective coupling cyclization of (2,3-butadienyl)malonate or bis(phenylsulfonyl)methane with propargylic carbonates was reported. The reaction proceeded smoothly under neutral conditions to afford the products in 73-96% yields. The products may be efficiently converted to cyclopentenone derivatives via a catalytic Pauson-Khand reaction under ambient conditions.
