phosphine-catalyzed remote 1,7-addition of vinyl allenoates has been developed, providing a series of 1,3-dienes derivatives in high yields (up to 99%) and with good chemo-, regio-, and stereoselectivity. This reaction demonstrated that the introduction of vinyl in allenoates effectively extended reaction types of phosphine-catalyzed nucleophilic addition of allenoates, leading to concise synthesis of diene carboxylates
已开发了膦催化的乙烯基异戊酸酯的远程1,7加成,可提供高收率(高达99%)且具有良好的化学,区域和立体选择性的一系列1,3-二烯衍生物。该反应表明,在烯丙酸酯中引入乙烯基有效地扩展了膦催化的烯丙酸酯的亲核加成的反应类型,从而导致二烯羧酸酯的简明合成。明显地,该1,7-加成的对映选择性变体也可以通过手性膦催化剂来进行。
