1-Methyl and 1-benzyl 3,5-bis(omega -haloalkyl) isocyanurates were reacted with thiourea to obtain 1-methyl and 1-benzyl 3,5-bis[omega-[amino(imino)methylmercapto]alkyl] isocyanurates, respectively. Hydrolysis of the latter gave the corresponding 3,5-bis(omega -mercaproalkyl) izocyanurates.
1-Methyl or 1-benzyl 3,5-bis(omega-bromoalkyl) isocyanurates with the alkyl chain comprising 3 through 6 methylene units were synthesized by the reaction of disodium methyl and benzyl isocyanurates with alpha,omega-dibromoalkanes. The reaction of disodium methyl and benzyl isocyanurates with ethylene chlorohydrin was used to obtain 1-methyl or 1-benzyl 3,5-bis(2-hydroxyethyl) isocyanurates whose treatment with PBr3 or SOCl2 gave the corresponding 1-alkyl 3,5-bis(2-haloethyl) isocyanurates. 1-Methyl and 1-benzyl 3,5-bis(chloromethyl) isocyanurates were prepared by treatment With SOCl2 of 1-methyl or 1-benzyl 3,5-bis(hydroxymethyl) isocyanurates obtained, in their turn, by condensation of methyl and benzyl isocyanurates with formaldehyde.

Reactions of 1,3-bis(omega-bromoalkyl)-substituted uracils, quinazoline-2,4-dione, and 5-methyl-1,3,5-triazine-2,4,6-trione and 1,3-bis(m-bromomethylbenzyl)-5-bromouracil with amines (aliphatic amines, benzylamines, naphthylmethanamine, and anisidine) gave a series of macrocyclic compounds having one pyrimidine or triazine fragment and an azapolymethylene bridge connecting the N-1 and N-3 atoms of the heteroring. The bridging nitrogen atom in some macrocyclic compounds was subjected to quaternization with methyl p-toluenesulfonate.
