    Chemoenzymatic synthesis and cytotoxicity of oenanthotoxin and analogues
    摘要:
    We developed a synthetic scheme for the synthesis of naturally occurring (14R)-oenanthotoxin and several analogs. Key-steps of this synthesis were an efficient homo-coupling of alkynes and a chemoenzymatic resolution of racemic oenanthotoxin using novozyme 435 and vinyl acetate. The compounds were screened for their cytotoxic activity using a photometric sulforhodamine B assays and several human tumor cell lines. Oenanthotoxin and many derivatives thereof were cytotoxic to tumor cell lines as well as to non-malignant mouse fibroblasts. The highest activity was determined for human ovarian cancer cells A2780 with EC50 = 3.8 mu M. (C) 2015 Elsevier Ltd. All rights reserved.

  • Acetylenic silyl ketone as polysynthetic equivalent of useful building blocks in organic synthesis
    作者:Antonella Capperucci、Alessandro Degl'Innocenti、Paolo Dondoli、Tiziano Nocentini、Gianna Reginato、Alfredo Ricci
    DOI:10.1016/s0040-4020(01)00578-6
    日期:2001.7
    Ethynyl silyl ketone 1 proved to be a very efficient Michael acceptor in carbocupration and metallocupration reactions. In particular, when using carbocuprates, a smooth entry to polyenals can be obtained, while, when using metallocuprates, silyl- and stannylpropenoyl silanes may be obtained, very powerful intermediates in organic synthesis.

    Structural variations in acylsilane molecules allow a number of new selective synthetic processes to be performed which lead to sulfur-containing heterocycles, highly functionalized and unsaturated polycarbonyl derivatives, polyenes, and β- and γ-aminoalcohols. The synthesis of these compounds, most of them not easily accessible through conventional routes, takes advantage of the site-selective reactions
    酰基硅烷分子的结构变化允许执行许多新的选择性合成工艺,这些工艺会导致含硫杂环,高度官能化和不饱和的多羰基衍生物,多烯以及β-和γ-氨基醇。这些化合物的合成(大多数都不易通过常规途径获得)利用C-Si键处发生的位点选择反应,相对于相应醛而言,酰基硅烷的稳定性提高以及SiR 3引入的非对面选择性团体。在本文中,我们报告了导致几种功能化酰基硅烷的合成及其合成应用的不同合成策略。还将介绍使用新的选择性多金属试剂进行亲核甲硅烷基化的方法。

    Methods of producing a 2,4-dienal acetal compound and a 2,4-dienal compound useful as synthesis intermediates of a sex pheromone compound having a conjugated diene structure or a conjugated triene structure. More specifically, a method produces a 2,4-dienal acetal compound of Formula (2): R 1 CH═CH—CH═CH—CH(OR 2 )(OR 3 ), including a step of subjecting a 2-enal acetal compound having a leaving group X at position C5 and being expressed by Formula (1): R 1 CHX—CH 2 —CH═CH—CH(OR 2 )(OR 3 ) to an elimination reaction in the presence of a base to obtain the 2,4-dienal acetal compound (2); and a method for producing a 2,4-dienal compound of Formula (3): R 1 CH═CH—CH═CH—CHO, further including a step of deprotecting the 2,4-dienal acetal compound (2) to obtain the 2,4-dienal compound (3).

  • The use of nitrones in the synthesis of anatoxin-a, very fast death factor
    作者:Joseph J. Tufariello、Harold Meckler、K.Pushpananda A. Senaratne
    DOI:10.1016/s0040-4020(01)96699-2
    日期:1985.1
    The synthesis of anatoxin-a (1) was completed by using the cycloaddition of 1-pyrroline 1-oxide (2) onto dienol (6), a reaction which proceeded with high stereoselectivity, regioselectivity, and site selectivity. The resultant adduct (i.e. 7) was oxidized to a second nitrone (i.e. 8) which undergoes a second closure to afford cycloadduct 9a with regiospecificity. The conversion of 9a into anatoxin-a
    Anatoxin-a(1)的合成是通过将1-pyrroline 1-oxide(2)环加成到二烯醇(6)上来完成的,该反应以高立体选择性,区域选择性和位点选择性进行。将所得的加合物(即7)氧化为第二硝酮(即8),将其进行第二次封闭以提供具有区域特异性的环加合物9a。将9a转化为盐酸Anatoxin-a(1 ·HCl)既直接又有效。
