  Asymmetric Total Synthesis of the 1-epi-Aglycon of the Cripowellins A and B

  摘要：

  [GRAPHICS]The unusual [5.3.2]-bicyclic structure of the insecticidal Amaryllidaceae alkaloids cripowellin A (1) and B (2) has been synthesized for the first time via a sequence of Sharpless dihydroxylation, ring-closing metathesis, and intramolecular Heck reaction. The asymmetric synthesis of the 1-epiaglycon 82 proceeds with virtually complete diastereo- and enantioselectivity (de, ee >= 98%) in 13 steps and an overall yield of 5.6%. In addition, three alternative approaches toward the aglycon 3 are also described focusing on (1) the alkylation of the 2-benzazepinedithianes 35 and 36 with the electrophile 11, (2) a radical cyclization of the precursor (R/S,S,S)-39, and (3) an intramolecular arylation reaction of the aryl ketone 47.

  Disubstituted (cyclohexadienyl)iron(1+) complex 2b is prepared by an improved route that starts from 1,2-dimethoxycyclohexa-1,4-diene 3. In five steps, the synthesis of 2b is achieved by complexation with Fe(CO)5, hydride abstraction, hydrolysis, addition of EtO2CCH2ZrBr, and reaction with HBF4. In the presence of dimethyl sulfide, the reaction of 2b with 2-[CH2N(CH2CH=CH2)2]-functionalized diarylcuprate

  双取代（环己二烯基）铁（1+）配合物 2b 是通过改进的路线制备的，该路线从 1,2-二甲氧基环己-1,4-二烯 3 开始。 分五步，通过与 Fe(CO) 络合来合成 2b 5、氢化物提取，水解，加入EtO2CCH2ZrBr，与HBF4反应。在二甲硫醚存在下，2b 与 2-[CH2N(CH2CH=CH2)2]-官能化的二芳基铜酸盐试剂 7 反应得到 5α-芳基环己二烯配合物 1b，产率为 88%。一项 DFT 研究比较了含有螯合 CH2NMe2 取代基的二芳基锌和二芳基铜酸盐试剂。
