Vilar, Juan,Quintela, Jose M.,Peinador, Carlos,Veiga, Carmen,Ojea, Vicente
, p. 2697 - 2706 (2007/10/02)
A convenient synthesis of 7-substituted 1,7,10-anthyridin-6-(7H)-ones using an enamination ring closure sequence is described.This strategy makes a novel, potencially universal method for the preparation of this new tricyclic ring system.
