A number of thermally and optically stable, bis-dipolar chiral molecules based on two geometries of the binaphthol (BN) system with different acceptors/substituents have been synthesized for the first time, and the synthetic routes are reported: optically pure 6,6‘-disubstituted 2,2‘-diethoxy-1,1‘-binaphthyls R, R‘= −Br, −CHO, −CHC(CN)(COOEt), −CHC(CN)2, −CHCHCN, −CHCH(p-NO2Ph)} and optically pure
首次合成了许多基于具有不同受体/取代基的联萘酚 (BN) 系统的两种几何结构的热和光学稳定的双偶极手性分子,并报道了合成路线:光学纯 6,6' -二取代的 2,2'-二乙氧基-1,1'-联萘 R, R'= -Br, -CHO, -CHC(CN)(COOEt), -CHC(CN)2, -CHCHCN, -CHCH(p -NO2Ph)} 和光学纯的 9,14-二取代二萘并[2,1-d:1',2'-f][1,3]dioxepins R, R' = -Br, -CHO, -CH=C (CN)(COOEt)、-CHC(CN)2、-CHCHCN、-CHCHSO2CH3、-CHCHCHO、-CHCHCHC(CN)2}。所有分子都具有两个相等的供体-受体系统,它们连接在一起形成双偶极系统。制备了两个单偶极 6-取代 2-丁氧基萘 (R = -CHC(CN)2, -CHC(CN)(COOEt)) 供体-
