Novel Polymer-Supported Coupling/Dehydrating Reagents for Use in Organic
Synthesis. — Two novel polymer-supported dehydrating agents (I) and (II) are prepared by reaction of the corresponding phosphine oxide with TFAA. The more suitable
component (II) is used for a wide range of coupling/dehydration-type reactions. With
primary alcohols, both reagents provide an alternative to the Mitsunobu reaction avoiding the use of azodicarboxylates and chromatography. (II) can also be applied to the
synthesis of peptides. — (FAIRFULL-SMITH, K. E.; JENKINS*, I. D.; LOUGHLIN,
