  Regiochemical control of the ring-opening of 1,2-epoxides by means of chelating processes. 2. Synthesis and reactions of the cis- and trans-oxides of 4-[(benzyloxy)methyl]cyclohexene, 3-cyclohexenemethanol, and methyl 3-cyclohexenecarboxylate

  摘要：

  The synthesis of the diastereoisomeric epoxides cis-1b-d and trans-2b-d and the products of their ring-opening by various nucleophiles are described. The results of the ring-openings of the trans-epoxides 2b-d can be rationalized by combining stereoelectronic and conformational arguments. However, the regioselectivity of the ring-openings of the cis-epoxides 1b-d can, in principle, be influenced by the chelation of a metal ion by the oxygen atom of the epoxy group and that of the substituent on the 4-position. The results of the reactions of the cis-epoxides 1b-d indicate that, to some degree, chelation is indeed a factor. How important a factor it is is dependent both on the reaction conditions and on the concentration and nature of the metal ion. In the ring-openings of the cis-epoxides 1b and 1d, chelation seems to be a larger factor than it is in the ring-openings of cis-epoxide 1c. However, in no case is chelation as large a factor as it was in the ring-openings of the cis-epoxide 1a, which was studied earlier. On the other hand, the autocatalyzed methanolysis, under neutral conditions, of epoxy acid 1e, followed by CH2N2 methylation of the crude product, afforded a mixture of the two regioisomeric hydroxy ethers in which the C-2-type compound predominates. This result suggests that intramolecular hydrogen bonding may determine the reactive conformation of 1e.

  Synthesis of diacylglycerol analogues as potential second-messenger antagonists and inhibitors of protein kinase C

  摘要：

  A series of analogues of diacylglycerol has been prepared and tested as inhibitors of protein kinase C (PKC). The diketone analogues, 10-hydroxymethyl-8,13-eicosanedione (24), 10-acetoxymethyl-8,13-eicosanedione (25), and 10-methoxymethyl-8,13-eicosanedione (26) each inhibited PKC activated by 2-0-acetyl-1-0-oleoylglycerol. Compound 24 was the most effective inhibitor of the growth of MR4 and HT29 cells in culture, and 26 was more effective than 24 against HL60 cells.

  cycloaddition of trans-cycloheptene (TCH) with tetrazine. Unlike the conventional strain-promoted bioconjugation reactions that utilize built-in strained alkenes as reactants, the current one features a “trigger-release-conjugate” reaction model, in which a highly strained TCH species is released from a bench-stable bicyclic N-nitrosourea (BNU) derivative upon treatment with an external stimulus. It is noteworthy

  开发概念新颖且实用的生物共轭反应一直是化学生物学研究的强烈追求。在此，我们报告了一种前所未有的生物共轭反应，该反应取决于反式环庚烯（TCH）与四嗪的化学触发反电子需求狄尔斯-阿尔德（IEDDA）环加成反应。与利用内置应变烯烃作为反应物的传统应变促进生物共轭反应不同，当前的生物共轭反应具有“触发-释放-共轭”反应模型，其中高度应变的TCH物质从工作台稳定的双环N-中释放出来。外部刺激后产生亚硝基脲（BNU）衍生物。值得注意的是，BNU 衍生物的反应性-稳定性平衡可以通过操纵其 N-1 取代基来调节。作为概念验证案例，这种新的化学触发 IEDDA 反应已应用于体外蛋白质标记和预靶向细胞成像。这项工作开辟了利用 BNU 衍生物作为生物共轭化学中新型化学报告分子的新途径。

  日期：2009.4

  A selective resin for linking trans-diequatorial-1,2-diols to solid support is described. This linking was carried out under mild and aprotic conditions involving the use of trimethylsilyl methyl ether in the presence of trimethylsilyl trifluoromethanesulfonate. Cleavage from the resin was also carried out under mild conditions by treatment with dichloromethane/trifluoroacetic acid/water (21:20:1). The usefulness of the described cyclohexane-1,2-diketone resin 7 in quinic acid chemistry was also studied. (C) 2009 Elsevier Ltd. All rights reserved.
