Application of aminopropyltriethoxysilane and N-[2-(aminoethyl)-N-3-(trimethoxysilyl)propyl]amine to the synthesis of linear and heterocyclic compounds

Reaction of 3-aminopropyltriethoxysilane and N-[2-(aminoethyl)-N-3-(trimethoxysilyl)propyl]-amine and their derivatives with diethylcarbamic acid trimethylsilyl ether and trimetisilylisocyanate proceeds through the stage of formation of intermediate products which under conditions of the synthesis undergo intramolecular (in the case of formation O-silylcarbamates) and intermolecular (in the case of the formation of carbamide trimethylsilyl derivatives) desilylation leading to the cyclic and linear products respectively.
