catalyst for reactions between anthrones and various dienophiles. The catalyst can tolerate a range of substituents and substitution patterns, making several anthrone derivatives suitable for this reaction. Both Diels-Alder and Michael adducts were obtained in excellent yields, high regioselectivities, and high enantioselectivities. This is the first case of a highly enantioselective base-catalyzed anthrone
手性双环胍 1 被发现是蒽酮和各种亲二烯体之间反应的极好催化剂。该催化剂可以耐受一系列取代基和取代模式,使几种蒽酮衍生物适用于该反应。Diels-Alder 和 Michael 加合物均以优异的产率、高区域选择性和高对映选择性获得。这是高度对映选择性碱催化蒽酮 Diels-Alder 反应的第一个案例。
