The solid-phasesynthesis of trisubstituted thiazoles is described. The synthetic strategy involves the formation of a polymer-bound thiazole by reacting resin-bound cyanodithioimidocarbonic acid and α-bromoketone. The resin-bound thiazole was reacted with acyl chlorides or isocyanates. After oxidation-activation of a thioether linker to a sulfone linker, traceless cleavage was achieved with nucleophiles
