微波固相合成苯并[a]吩噁嗪衍生物

Microwave Irradiated Synthesis of Benzo phenoxazine Derivatives in Solid State

首次在固相条件下微波辐射Ｎ，Ｎ－二烷基－４－亚硝基苯胺盐酸盐和２－萘酚衍生物快速合成苯并［ａ］吩嗪衍生物，得到苯并［ａ］吩嗪离子氯化物３ａ—３ｆ，且收率较高．此外，Ｎ，Ｎ－二甲基－４－亚硝基苯胺盐酸盐和１。

A new methodology quickly leading to benzo phenoxazine derivatives is reported. The mixture of N,Ndialkyl4nitrosoaniline hydrochloride and 2naphthol derivatives was irradiated in domestic microwave oven in the absence of solvent to afford benzoa]phenoxazonium chlorides 3a_3f with a high yield and the results were compared with the conditions reacted in supporters, oilbath or solvent. Moreover, a new laser dye 9dimethylamino6carbethoxy5Hbenzo phenoxazin5one was prepared.
