Arylimines of 1-tetralone (1) react with various substituted acetyl chlorides (2) in the presence of triethylamine yielding p-lactams spiroannulated with tetrahydronaphthalene (3). The stereochemistry of the products has been determined by NMR methods. Reactions of imines 1 with acid chlorides 2 were proved to be highly stereoselective.
