Boc-[20-C-6]-Bip-OMe 1, a new crown-carrier-α,α-disubstituted glycine with axial dissymmetry and a potential building block for the synthesis of polypeptide supramolecular devices, has been synthesized at the racemic state by phase transfer bis-alkylation of a glycine tert-butyl ester Schiff base with 2,2′-bis-(bromomethyl)-6,6′-dimethoxy-1,1′-diphenyl, followed by demethylation, esterification, N-protection and crown
Nt-Boc 6-氨基-1,11-(20-冠-6)-6,7-二氢-5H-二苯并[a,c]环庚烯-6-羧酸甲酯:Boc- [20-C-6 ] -Bip-OMe 1是一种新的具有轴向不对称性的冠状载体-α,α-二取代的甘氨酸,是多肽超分子装置合成的潜在组成部分,通过外消旋状态下的相转移双烷基化,已合成了外消旋状态。甘氨酸叔丁酯Schiff碱与2,2'-双-(溴甲基)-6,6'-二甲氧基-1,1'-二苯基,然后在二环环化后脱甲基,酯化,N-保护和形成冠生成的二酚的铯盐与五乙二醇二甲苯磺酸酯。
