  Step-Economic Synthesis of (+)-Crocacin C: A Concise Crotylboronation/[3,3]-Sigmatropic Rearrangement Approach

  摘要：

  The step-economic total synthesis of (+)-crocacin C has been achieved in 20% yield from commercially available starting materials. This approach requires the isolation of only 8 intermediates and can provide a reliable supply of (+)-crocacin C for the development of new antifungal and crop protection agents.

  （+）-crocacin C的全合成

  摘要：

  遵循收敛策略，实现了光学纯形式的（+）-crocacin C（3）的首次合成。合成还建立了这种新型的有效抗真菌和高细胞毒性化合物的绝对立体化学。天然存在的卡洛卡因C具有（6 S，7 S，8 R，9 S）构型，对于该家族的其他同类产品，卡洛卡星A，B和D也是相同的。

• Total Synthesis of (+)-Crocacin D

  DOI：10.1021/jo047732k

  日期：2005.3.1

  The total synthesis of (+)-crocacin D is described. The convergent asymmetric synthesis relies on the use of a Stille cross-coupling between an (E)-vinyl stannane with an (E)-vinyl iodide to establish the (E,E)-dienamide moiety followed by a mild and efficient copper-catalyzed coupling between (+)-crocacin C and a (Z)-vinyl iodide to establish the challenging (Z)-enamide function.

  Two approaches toward the total synthesis of cytotoxic polyketide natural product (+)-crocacin C (1) are described. The first approach, which was ultimately unsuccessful, was replaced altogether with a second that afforded target 1 in 10 linear steps from commercially available Evans' chiral propionimide (5% overall yield). No protecting groups were utilized in the total synthesis of 1. (C) 2010 Elsevier Ltd. All rights reserved.

  The total syntheses of crocacins A-D are described. The key steps were a syn-aldol reaction followed by anti-reduction to secure the stereo-tetrad and acylation of an ene- or dienecarbamate to form the enamide. Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.

  [GRAPHICS]The total synthesis of (+)-crocacin C is described. The convergent asymmetric synthesis relies on the use of a regio- and diastereoselective epoxidation of an allylic alcohol with m-CPBA followed by epoxide opening with Me2CuCNLi2 and a Stille cross-coupling between E-vinyl stannane 5 and E-vinyl iodide 6 to establish the (E,E)-dienamide moiety.
