  Total Synthesis of Oxazolomycin A

  摘要：

  The first total synthesis of oxazolomycin A, a structurally novel oxazole polyene gamma-lactam/beta-lactone antibiotic, is described. Key features Include the stereocontrolled construction of the right-hand heterocyclic core by taking advantage of an In(III)-catalyzed Conia-ene type cyclization and the asymmetric synthesis of the left-hand segment starting with a Cinchona alkaloid-catalyzed cyclocondensation of an aldehyde with an acid chloride.

  An effective method for the protection of carboxylic acids with a triisopropylsiloxymethyl (TIPSOCH2) group is described. The reactions of various carboxylic acids with C12H25SCH2OTIPS in the presence of CuBr2, Et3N, and molecular sieves 4A afford the corresponding triisopropylsiloxymethyl esters in good yields.

  描述了一种有效的保护羧酸的方法，该方法使用三异丙基硅氧烷甲基（TIPSOCH2）基团。在CuBr2、Et3N和4A分子筛的存在下，各种羧酸与C12H25SCH2OTIPS反应，得到相应的三异丙基硅氧烷甲基酯，其产率良好。

  The proposed structure of mohangic acid C (3) was stereoselectively synthesized via a catalytic asymmetric aldol reaction to install a p-aminoacetophenone moiety, Marshall propargylation furnishing two stereocenters, and Cu-mediated Stille-type coupling to construct the whole framework of 3.

• Stereoselective synthesis of the right-hand cores of 16-methylated oxazolomycins
  作者：Kohei Eto、Jun Ishihara、Susumi Hatakeyama

  DOI：10.1016/j.tet.2017.12.036

  日期：2018.2

  The right-hand heterocyclic cores of oxazolomycins having either 16R or 16S-methyl group configurations on the beta-lactones were stereoselectively synthesized from the common intermediate utilized for our previous syntheses of neooxazolomycin and oxazolomycin A. In addition, the right-hand segment required for the synthesis of KSM-2690 and lajollamycin members was also synthesized in a stereo-selective manner. (C) 2017 Elsevier Ltd. All rights reserved.
