new one-pot synthesis of 3-arylisoquinolines was accomplished by reaction of deoxybenzoins with an excess of nitriles and phosphorus pentoxide at room temperature. The usefulness of this synthesis was demonstrated by the facile preparation of 1-alkyl, 1-alkenyl, and 1-aryl substituted 3-aryl-isoquinolines and on a preparative scale. The effect of nitrile type and deoxybenzoin substitution pattern on
通过在室温下使脱氧安息香与过量的腈和五氧化二磷反应,可以完成3-芳基异喹啉的一锅合成。该合成的有用性通过1-烷基,1-链烯基,和1-芳基取代的3-芳基-异喹啉的制备容易表现出与在制备规模。研究了腈类型和脱氧安息香取代模式对环的可行性的影响。在大多数情况下,萘和嘧啶或作为副产物被分离出来。当类似地用三氯氧化磷代替五氧化二磷进行反应时,主要产物是氯二苯乙烯衍生物。
