Spirocyclohexylindolinone is used as a moiety in drug substances. A number of synthetic methods have been suggested to introduce the cyclohexyl ring into the C(3) position of N-protected indolinones, which complicates their preparation. A previously developed, consecutive, one-pot, multicomponent method is studied from a mechanistic aspect. We set out to clarify the details of this mechanism and the
螺环己基吲哚酮用作药物物质中的一个部分。许多合成方法已被建议将环己基环引入 N 保护的吲哚酮的 C(3) 位置,这使它们的制备复杂化。从机械方面研究了先前开发的、连续的、一锅多组分的方法。我们着手阐明这一机理的细节以及丙烯酸酯在同一烧瓶中作为试剂和保护基团的作用,通过使用理论和分析方法,以优化制备条件。在 DFT 理论水平计算反应的机械能量分布。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
