N-烷基-N-(2-乙烯基苄基)prop-2-en-1-胺衍生物经历一锅烯烃异构化/脂族烯胺闭环复分解(RCM)/氧化/ 1,3-偶极环加成序列,钌络合物Ru(CO)HCl(PPh 3)3,第二代Hoveyda-Grubbs催化剂和1,3-双极性亲和剂。总体而言,在一次操作中,反应序列通过三个独特的钌催化转化,将简单的苄胺衍生物转化为具有π共轭四环系统的异吲哚并[1,2- a ]异喹啉。
In all reactions studied up to the present time with olefins, the Reissert hydrofluoroborate salts have given only the Diels-Alder adducts. With 1,4-benzo- and naphtoquinones, we have found evidence for 1,3-dipolar cycloaddition. The structure of cycloadducts was determined from spectroscopic data and specified by a radiocristallographic study.
