Addition of 1,3,3-trimethyl-3,4-dihydroisoquinolines to N-benzylideneanilines gives substituted N-[2-(3,3-dimethyl-3,4- dihydroisoquinolin-1-yl)-1-phenylethyl]anilines, whereas 2',5',5'-trimethyl-4', 5'-dihydro- 4H-spiro[naphthalene-1,3'-pyrrol]-4-one reacts with N-benzylideneanilines along two pathways involving cyclization to substituted 2,3,3a,4,10,11-hexahydrobenzo[f]pyrrolo[2,3-d]quinolin-5(1H)-ones or elimination of the aniline residue with formation of substituted 5',5'-trimethyl-2-styryl- 4',5'-dihydro-4H-spiro[naphthalene-1,3'-pyrrol]-4-ones.
