Abstract
A new method for attaching aldehydes to solid supports has been developed employing a 2,2-bis(hydroxymethyl)propionic acid (DMPA) functionalized resin. High loading levels are obtained for both aryl and alkyl aldehydes protected as their respective acetals. Treatment of the derivatized resin with 95% TFA then cleanly affords the recovered aldehyde in high yield.

Abstract
There continues to be considerable effort towards the construction of compound libraries targeted for the inhibition of protease enzymes. New tag-encoding methods for library deconvolution have been applied to this problem and there has been particular interest in novel solid-phase linkers for the introduction of key pharmacophore groups required for protease inhibition. Recent reports have tended to focus on nonpeptidic libraries, and, notably, structure-based design methods are now being applied to direct library design.
