1-亚硝基萘酚-(2)重排为2-氰基肉桂酸的研究已见諸文献。但关于相应的异喹啉衍生物的合成及其重排反应尚未見记载。本文作者在研究分子重排的过程里,由7-羟基异喹啉(Ⅰ)经亚硝基化作用合成了7-羟基-8-亚硝基异喹啉(Ⅱ),熔点181.7—182.7℃;然后在氫氧化鈉在丙酮-水中的溶液里,用氯化苯磺酰处理产品,得β-[3-氰基吡啶基-(4)]-丙
Studies on the rearrangement of 1-nitrosonaphthol- (2) to 2-cyanocinnamic acid have been reported. However, the synthesis of the corresponding isoquinoline derivatives and their rearrangement reaction have not been described yet. In the process of molecular rearrangement, the authors synthesized 7-hydroxy-8-nitroso-isoquinoline (II) from nitrosation of 7-hydroxyisoquinoline (Ⅰ) with a melting point of 181.7-182.7 ℃ The product is then treated with chlorosulphonyl chloride in a solution of sodium hydroxide in acetone-water to give β- [3-cyanopyridyl- (4)] - C
