One?pot synthesis of arylmethylene Bis?3?hydroxy?2?cyclohexene?1?one? derivatives and xanthenedione derivatives

摘要

The present invention is an aryl -methylenebis (3-hydroxy -2- cyclohexene -1-one ) derivatives and glass tenda ion derivative of one- port relates to synthetic methods , and more particularly the present invention using a domino EDDA as a reaction catalyst - furnace through a Michael addition reaction and condensation reaction vena gel aryl -methylenebis ( 3-hydroxy- 2- cyclohexene -1-one ) derivatives like to be simple and efficiently - pot synthesis can also use the domino in (OTf) ₃ as a reaction catalyst - gel condensation reaction furnace vena Michael addition reaction and cyclization dehydration good cup tenda a simple, efficient ion derivatives through reaction won- pot can be synthesized
