  从天然脂肪酸对映体选择性合成蚊子产卵信息素及其差向异构体†

  摘要：

  蚊子产卵信息素（MOP）（5 R，6 S）-5-乙酰氧基-6-十六烷化物及其非天然（5 R，6 R）-非对映异构体的合成，其有机收率可达68％和54％。据报道天然存在的顺式-5-十六碳烯酸的环氧化和非对映异构的酯化反应。还讨论了动态动力学不对称转化（DYKAT）作为制备目标MOP的替代策略的研究，但是由于酮副产物的形成抑制了DYKAT过程中脂肪酶介导的乙酰化步骤，因此该方法未成功。

  Synthesis and Characterization of Novel Acyl-Glycine Inhibitors of GlyT2

  摘要：

  It has been demonstrated previously that the endogenous compound N-arachidonyl-glycine inhibits the glycine transporter GlyT2, stimulates glycinergic neurotransmission, and provides analgesia in animal models of neuropathic and inflammatory pain. However, it is a relatively weak inhibitor with an IC50, of 9 mu M and is subject to oxidation via cyclooxygenase, limiting its therapeutic value. In this paper we describe the synthesis and testing of a novel series of monounsaturated C18 and C16 acyl-glycine molecules as inhibitors of the glycine transporter GIyT2. We demonstrate that they are up to 28 fold more potent that N-arachidonyl-glycine with no activity at the closely related GlyT1 transporter at concentrations up to 30 mu M. This novel class of compounds show considerable promise as a first generation of GIyT2 transport inhibitors.

  the α oxidation of saturated, unsaturated, and heteroatom-containing (oxygen, sulfur) carboxylic acids 1 by the enzyme extract of peas (Pisum sativum) indicate that this biotransformation proceeds highly enantioselectively. For the first time, the synthesis of optically pure 2-hydroxy acids 2 has been achieved on the semipreparative scale (1 mmol) by α hydroxylation of long-chain carboxylic acids with
