  Synthesis of 3-substituted N-allylisoindolinone derivatives by the acetate method

  摘要：

  A series of N-allylisoindolinone derivatives were prepared by a novel sequential reaction of 2-allyl-3-oxoisoindolin-1-yl acetate with C-nucleophiles in the presence of trimethylsilyl trifluoromethanesulfonate. The nucleophiles included arenes, alkenes, and active methylene to give 3-substituted N-allylisoindolinone products. This method was applied to synthesize cyclohexane-fused indolizidine alkaloid mimics using Grubbs' catalyst..

  distinct feature of the trichloroacetimidate group allows use of weaker acid catalysts such as 1,1′-bi-2-naphthol (BINOL)-derived phosphoric acid, pointing out the possible development of an enantioselective variant. This unprecedented sequential one-pot Brønsted base-Brønsted acid catalysis further expands the synthetic scope of the trichloroacetimidate group.

  提出了一种新的连续两步多催化策略，该策略包括有效的DBU催化的醇的三氯乙酰亚胺化，然后由硅基亲核试剂和CH亲核试剂进行双三氟乙胺（Tf 2 NH）催化的分子间烷基化。三氯乙酰基亚氨酸酯基团的独特特征允许使用弱酸催化剂，例如1,1'-联-2-萘酚（BINOL）衍生的磷酸，指出了对映选择性变体的可能发展。这种前所未有的连续一锅法布朗斯台德碱布朗斯台德酸催化进一步扩大了三氯乙酰亚胺基的合成范围。
• A Multimetallic Piano-Stool Ir–Sn₃ Catalyst for Nucleophilic Substitution Reaction of γ-Hydroxy Lactams through <i>N</i>-Acyliminium Ions

  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.
