Abstract

Methods of preparing amino-substituted-tetrahydroisoquinoline ring compounds include the steps of providing a support-bound amino-substituted-tetrahydroisoquinoline compound; forming an intermediate by reacting the support-bound amino-substituted-tetrahydroisoquinoline compound with a reagent; and cyclizatively cleaving the support-bound amino-substituted-tetrahydroisoquinoline compound to form the amino-substituted-tetrahydroisoquinoline ring compound.
