    摘要:
    已经探索了几种亲电内酯化方法,作为通过相对不对称诱导官能化烯烃羧酸的方法,在热力学控制条件下,δ,β-不饱和酸的碘内酯化表现出良好的1,2-和1,3-,但1,4不-诱导δ-内酯的形成。巯基内酯化在形成γ-内酯和δ-内酯(1,2-诱导)时都具有良好的立体控制,但是在还原性脱汞过程中难以消除。用N-(苯基硒代)邻苯二甲酰亚胺进行的苯基硒代内酰胺化显然是动力学控制的,可对10(一种强空间偏向的底物产生δ-内酯)进行高诱导,而对16则不这样做。,导致生成γ-内酯。相反,在26(10的酯)的情况下,羟甲基内酯化在良好的立体控制下进行,而16的类似酯则没有。将由10和13的环化得到的内酯以立体特异性方式转化为(±)-sercorncornin的每种立体异构体。

    作者:Liang Wu、Shuifa Qiu、Guosheng Liu
    DOI:10.1021/ol900941t
    日期:2009.6.18
    A novel palladium-catalyzed intramolecular aerobic oxidative allylic C−H amination of olefins has been developed. Brønsted base can modulate the regioselectivity, favoring the formation of 7-membered rings. Mechanistic studies using deuterium-labeled substrates as probes support a rate-determining allylic C−H activation/irreversible reductive elimination pathway.

    A process of the present invention produces a hydroxylactone by subjecting an unsaturated carboxylic acid having a double bond not conjugated to a carboxyl group or an ester thereof to (i) a reaction with hydrogen peroxide in the presence of a metallic compound containing a metallic element selected from W, Mo, V and Mn or (ii) a reaction with a peroxide containing the metallic element to thereby yield a corresponding hydroxylactone having a hydroxyl group combined with one of carbon atoms constituting the double bond and being cyclized at the other carbon atom position. The metallic compound may be one selected from oxides, oxoacids and salts thereof. The unsaturated carboxylic acid includes, for example, &bgr;,&ggr;-unsaturated carboxylic acids, &ggr;,&dgr;-unsaturated carboxylic acids, and &dgr;,&egr;-unsaturated carboxylic acids.
