Popis: A series of novel chiral 5-(substituted aryl)-1,3,4-thiadiazole derivatives was synthesized in an enantioselective three-component Mannich reaction using cinchona alkaloid squaramide catalyst with excellent enantioselectivities (up to >99% enantiomeric excess (ee)). The bioassay results showed that these derivatives possessed good to excellent activities against tobacco mosaic virus (TMV).
