Regio- and catalyst selective imino Diels-Alder reactions of vinyl/isopropenyl pyrimidinones with N-arylimines in the presence of metal salts viz. magnesium(II) bromide, zinc(II) chloride, indium(III) chloride, yttrium triflate and scandium triflate, are described. An unprecedented oxidation of methylene to carbonyl has been shown to accompany the imino Diels-Alder reactions of isopropenyl pyrimidinones
乙烯基/异丙烯基嘧啶酮与 N-芳基亚胺在金属盐存在下的区域和催化剂选择性亚氨基 Diels-Alder 反应,即。描述了溴化镁(II)、氯化锌(II)、氯化铟(III)、三氟甲磺酸钇和三氟甲磺酸钪。在钇和三氟甲磺酸钪存在下,异丙烯基嘧啶酮的亚氨基 Diels-Alder 反应伴随着亚氨基向羰基的前所未有的氧化反应。在这些反应中用作催化剂的不同路易斯酸的化学选择性效应已被合理化。
