摘要

以杯[4]芳烃对叔丁基杯[4]芳烃1a为原料,用(R)-缩水甘油酯进行o -缩水甘油化反应,然后在溴化锂催化下用二氧化碳羰基化,合成杯[4]芳烃系四手性五元环碳酸酯1c。卟啉系链手性五元环碳酸酯2c也用类似方法合成。

Synthesis of calix[4]arene and porphyrin tethering four chiral five-membered cyclic carbonates.
Calix[4]arene tethering four chiral five-membered cyclic carbonates 1c was synthesized by O-glycidylation of p-tert-butylcalix[4]arene 1a with (R)-glycidyl tosylate, followed by carbonation with carbon dioxide catalyzed by lithium bromide. Porphyrin tethering chiral five-membered cyclic carbonates 2c was similarly synthesized.
