Polar polyoxyethylene-polyoxypropylene (POEPOP) resin, deriva-tized with a 4-hydroxymethyl phenoxy linker, was used as a solid support for lanthanide triflate-catalyzed Mukaiyama-type solid-phase aldol reactions.282 The use of an aqueous solvent was found to be crucial. The reactions on an N-terminal peptide aldehyde substrate proceeded in very high yields. [Pg.274]
