HClO4-SiO2在无溶剂条件下催化甲萘衍生物合成的探讨

HClO4--SiO 2 will catalyze the methyl naphthalene derivative synthesis under the non--solvent condition discussion

目的：寻找一条简单高效合成甲萘衍生物-8，10-二甲基-8，12-二氢-12-芳基-9～萘并[1’，2’：5，6]吡喃[2，3-d]嘧啶-9，11（10H）二酮的途径。方法：B-萘酚、芳基醛和1，3-二甲基巴比妥酸在HClO4-SiO2（3mool%）存在，无溶剂条件下进行反应。结果：该法有很好的收率。结论：找到了-条筒单高效且实用的合成方法。

Objective：Seeks simple highly effective synthesis methyl naphthalene derivative -- 8,10 -- dimethyt -- 8,12 -- di- hydro -- 12 -- aryl residue -- 9 -- naphtho-- [1 ＇,2 ＇：5,6] pyrane E2,3 -- d] pyrimidine -- 9,11（10H）two alkone way. Methods： Beta -- naphthol, the aryl residue aldehyde and 1,3-- dimethyl Barbitone acid 2 （3 mol%）exists in HClO4--SiP, under the non-- solvent condition carries on the response. Results ： This law has very well receives rate. Conclusion： Had found one simple highly ef- fective also the practical synthetic method.
