Abstract :
The solid phase synthesis of 3-(5′-carboxypentyl)-5-substituted tetrahydro-2H-1,3,5-thiadiazin-2-thione derivatives 5 is described. 6-Amino-n-hexanoic acid was attached via its C-terminal to hydroxymethyl polystyrene using a ‘SASRIN’ linker. The bound amino acid was converted to the corresponding dithiocarbamate 3 followed by cyclization in the presence of formaldehyde and the corresponding free amino acids to afford 3-(5′-carboxypentyl)-5-substituted tetrahydro-2H-1,3,5-thiadiazin-2-thiones 4. The final products were cleaved from the resin and obtained in moderate yields.
