A novel linker for the generation of alkyl-, acyl- and arylguanidines as an attachment point in solid phase synthesis has been developed. Introduction of a suitably functionalized thiourea to Wang resin via a carbamate linkage, followed by displacement of sulfur with a 1° or 2° amine affords resin bound guanidines suitably protected for further manipulation. Activation of the thiourea with Mukaiyama's
