  Total Synthesis of Sinenside A

  摘要：

  The first total synthesis of norlignan glucoside sinenside A has been accomplished. An intramolecular acetalization reaction has been employed as the key skeletal construct to forge the central cyclic disaccharide core. The trans-1,2-diol configuration present in the cyclic disaccharide of this natural product is unique and has been addressed by setting this configuration at the beginning. A 1,2-orthoester group has been selected as a handle for both sp glycosidation and for differentiation of the C2'-OH (that participates in the key acetalization reaction) of the sugar unit.

• Asymmetric Synthesis of Stagonolide-D and Stagonolide-G
  作者：Tridib Mahapatra、Tapas Das、Samik Nanda

  DOI：10.1246/bcsj.20100197

  日期：2011.5.15

  First asymmetric synthesis of the naturally occurring epoxy noneolide stagonolide-D has been reported in this article. Ring-closing metathesis (RCM) by Grubbs second generation catalyst, Sharpless asymmetric epoxidation (SAE), and cis-selective Horner–Wadsworth–Emmons (HWE) olefination by Ando method are the key reactions successfully employed to achieve the target molecule in a divergent approach. Structurally related small ring macrolide stagonolide-G has also been synthesized by employing RCM and a metal–enzyme combined dynamic kinetic resolution (DKR) strategy starting from (S)-ethyl lactate as a chiral pool.

  本文报道了天然环氧noneolide stagonolide-D的首次非对称合成。该合成通过使用第二代Grubbs催化剂的环合复分解（RCM）、Sharpless非对称环氧化（SAE）以及由Ando方法进行的顺式选择性Horner-Wadsworth-Emmons（HWE）烯化反应，成功地采用发散性途径合成了目标分子。从手性池来源的(S)-乳酸乙酯出发，利用RCM和金属-酶联合动态动力学拆分（DKR）策略，还合成了结构相关的小环大环内酯stagonolide-G。

  日期：2012.3.2

  The total synthesis of the putative structure of stagonolide D has been completed. The relative and absolute configuration of stagonolide D was established by synthesizing its optical antipode. The adopted strategy involves the construction of the central macrolide employing ring-closing metathesis (RCM), followed by selective protecting group manipulations and a final concomitant −OTBS deprotection

• Chemo-enzymatic asymmetric total synthesis of stagonolide-C
  作者：Nandan Jana、Tridib Mahapatra、Samik Nanda

  DOI：10.1016/j.tetasy.2009.10.007

  日期：2009.11

  The naturally occurring phytotoxic noneolide stagonolide-C has been synthesized by a chemo-enzymatic approach. Two key intermediates have been synthesized by applying a metal-enzyme combined DKR (dynamic kinetic resolution) strategy, followed by RCM (ring-closing metathesis) to afford the target compound in an efficient way.
