  Analogues of thiolactomycin as potential anti-malarial and anti-trypanosomal agents

  摘要：

  A series of analogues of the naturally occurring antibiotic thiolactomycin (TLM) have been synthesised and evaluated for their ability to inhibit the growth of the malaria parasite, Plasmodium falciparum. Thiolactomycin is an inhibitor of Type II fatty acid synthase which is found in plants and most prokaryotes, but not an inhibitor of Type I fatty acid synthase in mammals. A number of the analogues showed inhibition equal to or greater than TLM. The introduction of hydrophobic alkyl groups at the C3 and C5 positions of the thiolactone ring lead to increased inhibition, the best showing a fourteenfold increase in activity over TLM. In addition, some of the analogues showed activity when assayed against the parasitic protozoa, Trypanosoma cruzi and Trypanosoma brucei. (C) 2003 Elsevier Ltd. All rights reserved.

  condensation between a 1:1 mixture of carboxylic esters and acid chlorides promoted by TiCl4-Bu3N-N-methylimidazole proceeded successfully to give various beta-keto esters in good yields with excellent selectivities (19 examples, approximately 48-95% yield; cross/self-selectivity = approximately 96/4-99/1). The present method was extended to the condensation between a 1:1 mixture of carboxylic acids and carboxylic

  由 TiCl4-Bu3N-N-甲基咪唑促进的羧酸酯和酰氯的 1:1 混合物之间的 Ti-crossed-Claisen 缩合成功地以良好的收率和优异的选择性得到各种 β-酮酯（19 个例子，大约 48-95 % 产率；交叉/自选择性 = 约 96/4-99/1)。本方法扩展到羧酸和羧酸酯的 1:1 混合物之间的缩合（六个实施例，产率约 70-92%；交叉/自选择性 = 约 91/9-99/1）。为了证明目前两种 Ti 交叉克莱森缩合的效用，我们对两种天然、代表性和有用的香水顺式茉莉酮和 (R)-麝香酮进行了几次有效的短步合成。
