The reaction of various 3,4-dihydroisoquinolines with malonic acid gives the corresponding 1,2,3,4-tetrahydro-1-isoquinolineacetic acids in good yield, while the reaction with cyanoacetic acid and malonic acid half ethyl ester affords 1,2,3,4-tetrahydro-1-isoquinoline acetonitriles and 1,2,3,4-tetrahydro-1-isoquinolineacetic esters respectively. The use of other 1,3-dicarbonyls which cannot decarboxylate in this reaction affords the normal addition products.
各种 3,4-二氢异喹啉与丙二酸反应可以得到相应的 1,2,3,4-四氢-1-异喹啉乙酸,收率很高,而与氰基乙酸和丙二酸半乙酯反应则可以分别得到 1,2,3,4-四氢-1-异喹啉乙腈和 1,2,3,4-四氢-1-异喹啉乙酸酯。在此反应中使用其他不能脱羧的 1,3-二羰基,可得到正常的加成产物。
