The addition of organometallic reagents to the 13b-position of the indolo[2′,3′:3,4]pyrido[1,2-b]isoquinolineimminiumsalt 4 is described. Reaction of 4 with tetraallyl tin in 2-methoxyethanol gave the allyl adduct 7 in moderate yield. Further elaboration of 7 yielded the pentacyclic benzylidene alcohols 13 and 14. Structure elucidation of the compounds prepared was achieved by a combination of 1H
描述了将有机金属试剂添加到吲哚[2',3':3,4]吡啶并[1,2- b ]异喹啉亚胺盐4的13b-位。4与四烯丙基锡在2-甲氧基乙醇中的反应以中等收率得到烯丙基加合物7。进一步精制7,得到五环亚苄基醇13和14。通过1 H nmr光谱学和X射线晶体学的结合来阐明所制备化合物的结构。
