The 1,3-dipolar cycloaddition of azomethine ylide generated in situ from isatin and sarcosine to 5-arylmethylidene thiazolo[3,2-b][1,2,4]triazol-6(5H)- ones afforded novel 1'-methyl-4'-aryldispiro[indole-3,2'-pyrrolidine-3', 5a″-[1,3]thiazolo[3,2-b][1,2,4]triazole]-2,6a″ (1H)-diones in moderate yields. The structures of all the products were characterized thoroughly by NMR, infrared spectroscopy (IR), mass spectroscopy (MS) elemental analysis together with X-ray crystallographic analysis. © 2012 HeteroCorporation.
