Studies on the Synthesis of Sesamin-group Lignans IV.A Study of the Reaction between Dimethyl 2-Phenyl-furane-3,4-dicarboxylate and Grignard Reagents

研究了２－苯基呋喃－３，４－二羧酸二甲酯（２）与格氏试剂苯基溴化镁等（３）反应，生成酮基酸酯２－苯基－４－苯甲酰基呋喃－３－羧酸甲酯（１）的条件和方法。

In this paper,some preliminary results of the action of triethylamine on the re-action between dimethyl 2-phenyl-furane-3,4-dicarboxylate(2)and phenylmagnesiumbromides(3a-c)are reported. It was found that in the presence of triethylalnine, methyl 2-phenyl-4-benzoylfu-rane-3-carboxylates(la-c),and some-times also 2-phenl-3,4-dibenzoylfurane(4a)were formed.And, if no trietliylamine was added, methyl 2-phenyl-4-diphenyl-hydro-xymethyl-3-carboxylate(5a)was mainly formed.
