  A New Synthetic Route to β-Unsubstituted β-Lactones by Intramolecular Cyclization

  摘要：

  When carboxylic acids beta-substituted by a tert-butoxy group were treated with thionyl chloride, an intermediate acyl chloride beta-substituted by a hydroxyl group was likely formed. Its subsequent intramolecular cyclization produced novel beta-lactones in one step. Two enantiomerically enriched lactones could be prepared via intermediates obtained by enzymatic hydrolysis.

  超分子包合物对自由基1,2-重排的影响

  摘要：

  通过光解过酸酯前体在i)己烷溶液，ii)在β-环糊精存在下，和iii)在NaY沸石中。虽然溶液中的自由基不愿意重新排列，但当它们包裹在 β-环糊精或 NaY 沸石中时，它们就会重新排列。甲基丙二酰辅酶A 到琥珀酰辅酶A 的辅酶-B12 依赖性酶重排可以通过分子容器中假定的中间自由基类似物的光化学生成来模拟。

  A convenient and enantioselective synthesis of monoacetates of meso-1,3-diols 2-substituted with an alkoxymethyl or a thiophenylmethyl group, by enzyme catalyzed acylation, is described. The absolute stereochemistries of two monoacetates were assigned by chemical correlation. (C) 1998 Elsevier Science Ltd. All rights reserved.

  The free radicals 3-ethoxy-2-(ethoxycarbonyl)-3-oxopropyl (1.) and 3-ethoxy-2-(ethoxycarbonyl)-2-methyl-3-oxopropyl (2.) were generated by photolysis of perester precursors in i) hexane solution, ii) in the presence of β-cyclodextrin, and iii) in NaY zeolite. While free radicals in solution are reluctant to rearrange, they do so when encapsulated in β-cyclodextrin or NaY zeolite. The coenzyme-B12-dependent
