A new class of endocyclic enamines, 1,6-disubstituted 1,2,3,4,5,6,7,8- octahydro-1,6-naphthiridines, was synthesized from 4-piperidone imines by successive subjecting the latter to lithiation with lithium diethylamide, to alkylation with 1-bromo-3-chloropropane, and to intramolecular cyclization. All stages were carried out as a unique process without isolation of the intermediate compounds. A thorough optimization of the process conditions, workup, and product storage was carried out. The conformational study of 1,6-disubstituted 1,2,3,4,5,6,7,8-octahydro-1,6-naphthiridines was performed. Pleiades Publishing, Inc. 2006.

A simple and convenient synthetic approach to the new series of 1,2,3,4,5,6,7,8-octahydro-1,6-naphthyridines 1a-j has been developed. This was achieved via a one-pot process combining metalated 4-piperidinonimine alkylation and intramolecular cyclization.
