制备方法与用途

简介

3-丙亚基-1-异苯并呋喃酮又叫3-丁烯异苯并呋喃-1(3H)-酮,是一种含有不饱和双键的苯并呋喃酮衍生物。这类化合物在科研实验中具有重要作用,尤其是通过选择性氢化可以得到天然产物骨架,在医学和药学领域展现出潜在的价值,因此受到了广泛的关注。

制备

以邻碘苯甲酸甲酯(1 mmol,261毫克)与正丁炔(1 mmol,54毫克),在四三苯基膦钯3%、正丁胺(20%)和碘化亚铜(20%)的催化作用下,使用10 mL乙醚作为溶剂,在室温条件下发生偶联反应。得到偶联产物176 mg,收率为94%;随后在1 mol/L NaOH溶液(碱性条件)中以20 mL四氢呋喃为溶剂进行脱甲基反应,温度设定为60℃。通过过量的10%稀盐酸溶液酸化和分离后得到苯甲酸化合物160 mg,收率为98%;最后,在10 mL甲苯作为溶剂中、温度控制在80℃下使用5% DMAP进行一步成环反应,最终获得3-丙亚基-1-异苯并呋喃酮154 mg,收率为96%。

    The present application discloses novel PWNN and PWNWP metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, enals, enones, enolates, oils and fats, resulting in alcohols, enols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.
    本申请披露了用于有机化学合成的新型PWNN和PWNWP金属催化剂,包括不饱和化合物的加氢(还原)或底物的脱氢。加氢底物化合物的范围包括酯,内酯,烯醛,烯酮,烯醇酸盐,油和脂肪,产生醇,烯醇,二醇和三醇作为反应产物。当前申请的催化剂可用于在无溶剂条件下催化加氢反应。目前的催化剂还允许加氢反应在无添加碱的情况下进行,并可用于取代使用主族元素氢化物的传统还原方法。此外,本申请的催化剂可以在均相和/或无受体条件下催化脱氢反应。因此,本文提供的催化剂可以在大幅降低成本和改善各种化学品制造过程的环境概况方面发挥作用。
