Several approaches for the synthesis of the title compound 1 were investigated. Treatment of the ethane-1,2-diamine derivative 2 with phosphoryl chloride afforded 3-chloro-5,5-dimethylcyclohex-2-enone (3) and 1-(5,5-dimethyl-3-oxocyclohex-1-enyl)-4,5-dihydro-2-phenylimidazole (4), The reaction of 2-benzoyl-dimedone (5) with an equimolar amount of ethane-1,2-diamine led to the 2:1 adduct 6, whereas
研究了标题化合物1的几种合成方法。用磷酰氯处理乙烷-1,2-二胺衍生物2,得到3-氯-5,5-二甲基环己-2-烯酮(3)和1-(5,5-二甲基-3-氧代环己-1-烯基) -4,5-二氢-2-苯基咪唑(4),2-苯甲酰基二甲酮(5)与等摩尔量的乙烷-1,2-二胺的反应生成2:1加合物6,而过量得到乙烷-1,2-二胺,4,5-二氢-2-苯基咪唑(7)和二甲酮。标题化合物1的合成是通过使2-苯甲酰基-3-氯-5,5-二甲基环己-2-烯酮(8)反应而完成的 与乙烷1,2-二胺。
