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.
