ABSTRACT:
The present invention relates generally to cyclosporin analogs, and more paritcularly to methods for the solid-phase synthesis and on-resin cyclization of cyclosporin analogs. Methods are described for the on-resin cyclization of sterically hindered compounds synthesized through solid phase synthesis techniques. The methods utilize solvent, temperature, and washing conditions that allow the efficient on-resin cyclization of compounds like analogs of cyclosporin A.
