A toolkit of low molecular weight MPEG-supported coupling agents (MIIDQ, MEDCI), reagents for the Mitsunobu reaction (MDEAD, MTPP), an alternative to diazomethane, and scavengers can be used in the solution-phase synthesis of amides, esters and ureas and are easily removed after use by solid-phase extraction (MSPE) using normal silica.
A fluorous isatoic anhydride and isocyanate are synthesized and used as scavengers for amines in solution-phaseparallelsynthesis of urea, thiourea, and β-hydroxyamine analogs. The resulting fluorous derivatives are readily separated from the reaction mixture by solid-phase extractions (SPE) over FluoroFlash™ cartridges to give products with good purity. The SPE cartridges can be reused.
