Expanding the utility of one-pot multistep reaction networks through compartmentation and recovery of the catalyst

Controlled catalysis: The combination of magnetically and gravimetrically recoverable catalysts such as the nanoparticle-bound base (see picture; blue) and the resin-bound acid (green), respectively, allow the application of non-complementary catalysts to multistep, one-pot reaction cascades (e.g. A→B→C). The catalysts are recovered after reaction and reused in subsequent, unrelated reactions. (Figure Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
