摘要:In its first aspect, the invention is directed to a solid support mediated method for the synthesis of diverse polycyclic heterocycles according to general formula (V). A second aspect of the invention is directed to a solid support bound intermediate compound that optionally can be derivatized before a cyclization and displacement procedure provides a product. The intermediate is preferably stable to a wide range of chemical conditions thus allowing, if desired, for the chemical derivatization of the intermediate. A third aspect of the invention is directed to a library of polycyclic heterocycle compounds where said library contains a plurality of diverse library compounds of general formula (V). A fourth aspect of the invention is directed to a method for the synthesis of a library of diverse polycyclic heterocycles by the general method described. A fifth aspect of the invention is directed to an assay kit for the identification of lead compounds of the library described therein.
