Phosphazene base-catalyzed hydroamination of aminoalkenes for the construction of isoindoline scaffolds: Application to the total synthesis of aristocularine
A method for isoindoline synthesis via phosphazene base-catalyzed intramolecular hydroamination of aminoalkenes was developed. The reaction has a broad functional group tolerance, including for halide, cyano, and methoxy groups, and could also be used to synthesize tetrahydroisoquinoline, pyrrolidine, and piperidine. The method was used as a key step in the total synthesis of aristocularine in six
建立了磷腈碱催化氨基烯烃分子内加氢胺化合成异二氢吲哚的方法。该反应具有广泛的官能团耐受性,包括卤化物、氰基和甲氧基,也可用于合成四氢异喹啉、吡咯烷和哌啶。该方法被用作马兜铃碱全合成的关键步骤,分六步进行,总产率为 35%。该策略涉及通过控制所需 C N 键的形成来构建异二氢吲哚核心,而相对不稳定的甲氧基甲基和芳基溴保持完整。

The photophysical and photochemical behavior of a series of secondary and tertiary ω-(β-styryl) aminoalkanes with one to five methylenes separating the styryl and amino groups has been investigated and compared to the intermolecular reactions of 1-phenylpropene with secondary and tertiary amines. The effects of polymethylene chain length, solvent polarity, temperature, and the bulk of the N-alkyl group
