Abstract: The present invention provides compounds of the Formula I and II: wherein R1, R3, W, Z, X1, X2, Ar1, R8 and R9 are as defined herein, and methods and intermediates for their preparation and uses thereof.

Abstract: The invention provides systems and methods for synthesizing various compounds on solid support. According to one exemplary method, a synthesizer is provided having at least one reaction vessel block with a plurality of reaction vessels therein. At least one solid support is introduced into a least some of the reaction vessels, and a reagent is introduced into the reaction vessels having the solid supports. The reaction vessel block is then vibrated while heat is supplied to the reaction vessel block to heat the reaction vessels. Optionally, the synthesized compounds may be cleaved from the solid supports following synthesis while they remain within the reaction vessels.
