The reaction of the functionalized N‐protected imines 3 and 7 containing either the chloromethyl or ethyl ester moieties, respectively, attached to the imine carbon with homophthalic anhydride 2 afforded cis/tran‐3‐subsituted‐1‐oxo‐1,2,3,4‐tetrahydroisoquinoline‐4‐caboxylic acids appropriate for further synthetic elaboration.
功能化的N保护的亚胺3和7分别含氯甲基或乙基酯部分与亚胺碳与高邻苯二甲酸酐2的反应得到顺式/反式-3取代的1-氧代1,2,3 ,4-四氢异喹啉-4-羧酸适合进一步合成。
