Efficient cleavage-cross-coupling strategy for solid-phase synthesis-a modular building system for combinatorial chemistry.

A new modular building system for the combinatorial chemistry was developed on the basis of triazene linkers. Starting from an aniline system, further functional units and virtually any alkene or alkyne as terminator furnished lipophilic multicomponent systems in high yields and purities without the need for purification steps (see schematic representation).
