4,5-二芳基噁唑的光化学环化消除合成菲并[9,10-d]噁唑

SYNTHESIS OF PHENANTHRO [9, 10-d] OXAZOLES BY PHOTO-CYCLOELIMINATION OF 4,5-DIAROMATIC SUBSTITUTED OXAZOLES

具有异芪生色团结构的分子是有机光化学研究的重要对象。4,5-二芳基嗯唑(1)具有部分结构与异芪类似,本文对其分子内环化消除过程和产物进行了研究。 本文认为1的环化消除过程如下:

The photo-cycloelimination of 4,5-diaromatic substituted oxazoles was investigated.The reaction mechanism was discussed with the Woodward-Hoffmann rule and free valence theory,respectively Three phenanthro (9,10-d) oxazoles were synthesized and characterized.
