containing one scaffold subunit were obtained from 1,6-dibromohexane, 1,5-dichloro-3-oxapentane, 1,11-dibromo-3,6,9-trioxaundecane and 9,10-bis(chloromethyl)anthracene. Larger alicyclophanes incorporating two spacer subunits were formed by intermolecular cyclisation of 5 with 1,2-dibromoethane or 19 with m- or p-xylylene dibromide. Reaction of 5 with propargyl bromide, followed by oxidative coupling (CuCl)
降冰片基琥珀酰亚胺已与2,5-双(三氟甲基-1,3,4-恶二唑)立体选择性偶联,制备脂环式骨架5和20,端基5的琥珀酰亚胺-氮与双烷基化剂的烷基化反应在短时间内产生了大环化合物含有一个支架亚基的脂环烷是从1,6-二溴己烷,1,5-二氯-3-氧杂戊烷,1,11-二溴-3,6,9-三氧杂十二烷和9,10-bis( 。氯甲基)蒽结合两个间隔亚基更大alicyclophanes通过分子间环化形成5与1,2-二溴乙烷或19与米或- p。-xylylene二溴化物反应5用炔丙基溴,然后通过乙炔侧基的氧化偶联(CuCl)提供双炔基脂环族13。
