  Synthesis of cycloprop[c]indol-5-ones from 4-diazo-3-[n-(2-propenyl)amido]cyclohexadien-1-ones. Exploration of copper(I) and copper(II) complexes as catalysts

  摘要：

  The cyclization of 4-diazo-3-[N-(2-propenyl)amido]cyclohexadienones to cycloprop[c]indol-5-ones under the influence of copper(I) and copper(II) compounds has been investigated. Catalysis is observed with copper(I) triflate, the carbon monoxide complex of copper(I) triflate, and the carbon monoxide complexes of trifluoropentanedionato- and hexafluoropentanedionatocopper(I). The best results, essentially quantitative conversion, are achieved with a catalyst solution containing trifluoropentanedionatocopper(I) carbonyl and 1 equiv of n-butylamine. No significant enantioselectivity is observed with a chiral salicyliminatocopper(II), [(trifluoroacetyl)camphorato]copper(I) carbonyl, or a trifluoropentanedionatocopper(I) carbonyl solution containing (S)-alpha-naphthylethylamine. A mechanistic interpretation involving reductive dediazonization, exo-trig radical cyclization, and cyclopropane formation by the resulting intermediate is proposed.

  was employed to control the absolute stereochemistry of the C6 quaternary center. The complementary diastereoselectivity of a thermodynamic versus kinetic condensation of 61 permitted the divergent synthesis of (+)-duocarmycin A or epi-(+)-duocarmycin A from common intermediates. Final introduction of the reactive cyclopropane was accomplished by transannular spirocyclization of the mesylate 44 upon treatment

  描述了 (+)-duocarmycin A (1) 的对映选择性全合成的全部细节，其中提供了控制远程立体中心的相对和绝对立体化学的解决方案。采用 15 的催化不对称二羟基化来引入活化环丙烷所需的绝对立体化学，并采用 61 的非对映选择性 Dieckmann 型缩合来控制 C6 季中心的绝对立体化学。61 的热力学与动力学缩合的互补非对映选择性允许从常见中间体合成 (+)-duocarmycin A 或表 - (+)-duocarmycin A。反应性环丙烷的最终引入是通过甲磺酸酯 44 在用碱处理或直接从相应的游离醇本身、duocarmycin D1 (42) 处理后，在 Mitsunobu 活化后的跨环螺环化来完成的。值得注意的是，使用 (DHQD)2-PHAL/(DHQ)2-PHAL 的 15 的不对称二羟基化...
