Reactions of styrylmalonates with aromatic aldehydes in the presence of Lewis and Brønsted acids and their regularities have been studied in detail. Approaches to the synthesis of various polysubstituted 5,6-dihydropyran-2-ones, indenes, aryl-containing dienes and trienes, cyclopentadienes, and polycyclic lactones have been developed with chemo-, regio-, stereo-, and diastereoselectivity control. The
详细研究了路易斯酸和布朗斯台德酸存在下,丙二酸苯乙烯基丙酸酯与芳香醛的反应及其规律性。已经开发了具有化学,区域,立体和非对映选择性控制的各种多取代5,6-二氢吡喃-2-酮,茚,含芳基的二烯和三烯,环戊二烯和多环内酯的合成方法。使用多核NMR实验深入研究了这些反应的机理,监测了NMR管中的反应以及18 O同位素标记。
