A novel cleavage technique to generate small molecule compounds and libraries via a two-resin system

Application of organic synthesis to solid supports has led to the successful implementation of combinatorial chemistry in the drug discovery process. This paper describes a novel use of the Hofmann elimination of tetrasubstituted amine salts on solid-phase resin to generate diverse combinatorial libraries of trisubstituted amines. Highly pure compounds were isolated without further purification by the addition of a second resin as the source reagent to promote the required elimination. The use of mixed resin systems to generate compounds is a novel application of bead-based technologies.
