main side product, the HMB isomer, may be an interesting intermediate for the synthesis of calone analogues, which are important scaffolds used in fragrances. A detailed mechanistic study, supported by kinetics, GC-MS, and HMBC NMR characterization, is also reported. Accordingly, this paper describes a completely innovative and greener synthesis pathway to benzodioxanes.
本文研究了碳酸甘油酯(GlyC)作为酚类化合物的创新性和高反应性烷基化剂的独特反应性。特别是,在碱性催化剂(NaOCH 3, Na-丝光沸石,MgO),无需反应溶剂。在均相碱性催化剂(NaOCH 3)。值得注意的是,主要副产物HMB异构体可能是合成calone类似物的有趣中间体,calone类似物是香料中使用的重要骨架。还报道了详细的机理研究,并得到动力学,GC-MS和HMBC NMR表征的支持。因此,本文描述了一种完全创新且更绿色的苯并二恶烷合成途径。
