xanthen-9-ol and thioxanthen-9-ol with indoles has been developed, providing an efficient procedure for the synthesis of xanthene/thioxanthene-indole derivatives with good to excellent yields. This protocol offers several advantages, such as short reaction times, green solvent, operational simplicity, easily available catalyst and mild reaction conditions. Moreover, this method showed good tolerance of functional

A series of 9-[(aminoalkyl)thio]-9H-xanthenes (3-6) and 5-[(aminoalkyl)thio]-5H-[1]benzopyrano[2,3-b]pyridines (7-10) possessing gastricantisecretory activity in the rat and dog is described Many of the compounds possessed good activity in the pylorus-ligated rat and several inhibited histamine-stimulated gastric acid secretion in the dog. The mechanism of acid secretion inhibition is not related
