酰基和茚满酮型双苯并冠醚的合成

THE SYNTHESES OF NEW DIBENZO-CROWN ETHERS

以多聚磷酸（ＰＰＡ）为催化剂和溶剂，合成了卤代乙酰基二苯并冠醚（Ａ，Ｂ，Ｃ）和茚满酮型二苯并冠醚（Ｄ，Ｅ，Ｆ）．这６种产物均由ＩＲ．Ｖ，ＭＳ．１３Ｃ—ＮＭＲ和元素分析鉴定得到证实．

The condesation reaction of dibenzo-24-crown-8 with haloacetic acids inpolyphosphoric acid agve A, B and C. Compounds D, E and F were obtained from dibenzo-24-crown-8 and unseturated acids with polyphosphoric acid as catalyst in one step. The six productswere characterized by elemental analysis, IR,UV,MS and 13CNMR.
