Abstract A thiouronium-based solid-phase synthesis of a 1, 3, 5-triazine scaffold has been developed. The key feature of the synthesis is the use of a readily accessible solid- supported thiouronium salt as a primary precursor for the stepwise assembly of the 1, 3, 5- triazine substrate. The sulfur linker employed in the synthesis is stable under both acidic and basic conditions and is versatile enough to provide access to monocyclic, bicyclic, and ...
