A simple method for coupling aldehydes to solid support
摘要:
A new method for attaching aldehydes to solid supports has been developed employing a 2,2-bis(hydroxymethyl)propionic acid (DMPA(R)) 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. (C) 1998 Elsevier Science Ltd. All rights reserved.
