✦ Synopsis


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

Short pathways are described for the synthesis of a representative example of each of the 7,8-dihydroand 1,2,3,4-tetrahydro-1,6-naphthyridine-5(6H)-one ring systems from simple pyridine precursors. An attempted synthesis of the related 4,6-dihydro-1,6-naphthyridin-5(1H)-one ring system from a common
