Abstract

[GRAPHICS]The high-yielding synthesis and application of the first example of a polymer-supported reagent for the preparation of trifluoromethanesulfonates (triflates) is described. This new reagent efficiently triflates aryl alcoholsand lithium enolates in high yield (>90%). A simple precipitation and filtration to remove the excess reagent and byproduct facilitate purification of the triflate products. The PEG-supported approach is highly efficient, asthe PEG-supported byproduct can be quantitatively recovered and recycled into reagent 1.
