title: A simple method for coupling aldehydes to solid support.
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.
