Abstract

A series of xanthenediones, 3 were synthesized from benzyl alcohols, 1 via TEMPO/CuCl₂ catalyzed aerobic oxidation, and sequential cyclization with cyclohexane-1,3-dicarbonyl compounds has been achieved. Similarly, the acridine-diones, 5 were obtained using a similar strategy from various benzyl alcohols. The strategy offers a simple experimental procedure, ease of access, within short reaction period, without the use of any hazardous solvents, and expensive chemicals.

TEMPO/CuCl2催化苯甲醇有氧氧化和环己烷-1,3-二羰基化合物环化简便合成吖啶二酮和吖啶二酮

摘要

一系列呫吨二酮类化合物，3个由苯甲醇合成，1个通过TEMPO/CuCl ₂催化有氧氧化，并与环己烷-1,3-二羰基化合物连续环合。类似地，吖啶二酮类化合物5是使用类似的策略从各种苯甲醇中获得的。该策略提供了一个简单的实验程序，易于访问，在很短的反应时间内，不使用任何危险溶剂和昂贵的化学品。
