苯甲叉基丙二腈与间苯三酚反应产物结构的辩证

Rectification of the Product Structure of the Reaction of Phenylmethylenepropanedinitriles and Phloroglucinol

苯甲叉基丙二腈与间苯三酚反应产物结构的辩证鲁宽科，谭镇，李裕林（兰州大学化学系，兰州，７３００００）关键词香豆素，黄烷酮，结构文献［１，２］报道了柚皮素（Ｎａｒｉｎｇｅｎｉｎ）、乔松素（Ｐｉｎｏｃｅｍｂｒｉｎ）等１２种黄烷酮的合成路线，认为其反应过程...

The conclusion of the paper on synthesis of flavanone(see Chem.J.ChineseUniv.1987,8(10):914)was tested to be uncorrect.Phloroglucinol reacted with p-hydrox-y-phenemethylenepropanedinitrile and phenylmetliylenepropanedinitrile respectively to give 3,4-dihydro-5,7-dihydroxy-4-(p-hydroxyphenyl)-coumarin(Ⅲ)and 3,4-dihydro-5,7-dihy-droxy-4-phenylcoumarin(Ⅳ),but not to give Naringenin and Pinocembrin.
