摘    要:用THF作为反应溶剂, K2CO3作碱, 对-叔丁基杯[6]芳烃与二溴丁烷、二溴己烷和1,4-二氯丁炔-2反应以中等产率选择性地合成了含有卤素端基的单取代对-叔丁基杯[6]芳烃2a2c. 2a2b可与对甲苯磺酸甲酯(MeOTs)反应高产率地得到全甲基化产物3a3b. 通过核磁共振谱(1H NMR)和质谱(FAB-MS)表征, 发现所有化合物都具有预期结构, 2a2c3b在室温下是锥式构象, 而3a没有固定构象.

关 键 词:杯[6]芳烃  单功能化  甲基化  构象

Abstract:Three mono-substituted p-tert-calix[6]arenes (2a2c) with terminal halogen groups have been synthesized by treating p-tert-calix[6]arene with Br(CH2)4Br, Br(CH2)6Br or ClCH2C≡CCH2Cl in THF using K2CO3 as base in moderate yield, respec-tively. 2a and 2b could be further converted to 3a and 3b in high yields by MeOTs. Their structures and conformations were characterized by 1H NMR and MS spectra. It was concluded that 2a2c and 3b existed in cone conformation at room temperature, but no confined conformation of 3a was observed.
Keywords:p-tert-calix[6]arene  mono-functionalization  methylation  conformation
