t-BuOK-catalyzed cyclization of 2-chloroquinoline-3-carbonitriles with guanidine hydrochloride provided simple and rapid synthesis of 2-amino-3H-pyrimido[4,5-b]quinolin-4-ones in very short reaction time with good yield. Other 1,3-binucleophiles are found to react at the same rate. This methodology could be extended with their 3-formyl and 3-ester derivatives for the synthesis of pyrimido annulated quinolines.

Vilsmeier-Haack reagent: A facile synthesis of 2-chloro-3-formylquinolines from N-arylacetamides and transformation into different functionalities

A simple and regioselective synthesis of 2-chloro-3-formylquinolines through Vilsmeier-Haack cyclisation of N-arylacetamides has been reported. The cyclisation is facilitated by N-arylacetamides bearing electron donating groups at m-position. However, yields of quinolines having electron donating groups are good in all cases. Further, the nucleophilic substitution reaction of the quinolines is also investigated. Similarly, the formyl group in the quinolines is subjected to further transformation into cyano (CAN-NH3) and alkoxycarbonyl (NIS-K2CO3/alcohols) groups to afford corresponding 3-cyano and 3-alkoxycarbonylquinolines, respectively.
