%X The green synthesis of some indeno[2`,3`:5,6]pyrido[2,1-b]benzothiazoles (4a-f) and indeno[2`,3`-e]thiazolo[3,2-a]pyridines (6a-f) via a one-pot, three-component reaction of indan- 1,3-dion (1), aromatic aldehydes (2a-f), (benzothiazol-2-yl)acetonitrile (3) or 2-cyanomethyl-4- thiazolinone (5), and catalyzed by p-toluene sulfonic acid (p-TSA) using water as reaction medium is reported.
