  A Multimetallic Piano-Stool Ir–Sn₃ Catalyst for Nucleophilic Substitution Reaction of γ-Hydroxy Lactams through N-Acyliminium Ions

  摘要：

  A multimetallic piano-stool complex [Cp*Ir-(SnCl3)(2){SnCl2(H2O)(2)}] (1) having Ir-Sn-3 motif has been synthesized from [Cp*IrCl2](2) and SnCl2. The multimetallic complex catalytically promotes the nucleophilic substitution reaction (here after alpha-amidoalkylation reaction) of gamma-hydroxylactams generated from phthalimidals to obtain decorated isoindolinones in excellent yields. Succinamidals, however, lead to the substituted pyrrolidinones (thermodynamic control product) via S(N)1-type path as well as eliminated pyrrolinones (kinetic control product) via an E1-type path, depending on the reaction parameters. A straightforward application of this methodology is to synthesize benzo-fused indolizidine alkaloid mimics.
