An improved synthesis of the 3-[3-(p-substituted
phenyl)-1,2,3,4-tetrahydro-1-napththyl]-4-hydroxycoumarins, diphenacoum
and brodifacoum, is described. The process is primarily based on the
formation of one of the crucial bonds in the carbon backbone using
organocopper methodology, and on the coupling of the 4-hydroxycoumarin
moiety to the 3-biphenyl tetralin unit under strongly acidic
conditions.
描述了一种改进的3-[3-(对取代苯基)-1,2,3,4-四氢-1-萘基]-4-羟基香豆素、联苯敌鼠和溴敌隆的合成方法。该过程主要基于使用有机铜方法形成碳骨架中的关键键,并在强酸性条件下将4-羟基香豆素部分与3-联苯四氢萘单元耦合。
