p-nitryl chlorine benzyl formate

Solvent-free manufacturing process research on high pure benzyl chloroformate

高纯氯甲酸苄酯无溶剂生产工艺的研究

A simple and efficient method has been reported by following a close pH control between 2 and 3 during slow addition of benzyl chloroformate to give the symmetrically 1,7-diprotected 1,4,7,10-tetraaza- cyclododecane (cyclen) derivative 1,7-bis(benzyloxycarbonyl)-cyclen (4).

在酸性条件下(pH=2～3),1,4,7,10-四氮杂环十二烷(Cyclen)和氯甲酸苄酯反应,得到高选择性1,7-二保护Cyclen衍生物1,7-二(苄氧基羰基)-1,4,7,10-四氮杂环十二烷(4),然后在二异丙基乙胺作用下和化合物1-苄氧基-4-(2-溴乙氧基)苯(2)一锅法有效合成了中间体1,7-二(2-对苄氧基苯氧基)乙基-4,10-二(苄氧基羰基)-1,4,7,10-四氮杂环十二烷(5)和4-(2-对苄氧基苯氧基)乙基-1,7-二(苄氧基羰基)-1,4,7,10-四氮杂环十二烷(6),在乙醇溶液中经Pd/C催化氢解得到两种新型的用取代苯酚基修饰的Cyclen衍生物1,7-二(2-对羟基苯氧基)乙基-1,4,7,10-四氮杂环十二烷(7)和1-(2-对羟基苯氧基)乙基-1,4,7,10-四氮杂环十二烷(8),其结构经1HNMR,IR和MS确证。
