Novel examples for dipolar cycloaddition of isoquinolinium ylides to nitriles leading to new imidazo[2,1-a]isoquinolines were described and the potential of this reaction in synthetic chemistry was explored. As a by-product of this research, a number of N-substituted, 3,4-dihydro-1H-isoquinoline-1-carbonitriles were synthesized by a simple, efficient reaction of a series of isoquinolinium bromides
描述了异喹啉叶立德与腈的偶极环加成产生新的咪唑并[2,1- a ]异喹啉的新例子,并探索了该反应在合成化学中的潜力。作为本研究的副产品,通过一系列异喹啉溴化物和氰基甲酸乙酯在存在下进行简单、高效的反应,合成了许多N-取代的 3,4-二氢-1 H-异喹啉-1-甲腈。三乙胺。
