Acidic and basic sites can be isolated by incorporation in the core of star‐shaped polymers (see picture). Fréchet, Hawker, and co‐workers have used these polymer‐based catalysts for homogeneous‐phase one‐pot multistep reactions. Similarly, Kaneda et al. have demonstrated the site‐isolation concept in heterogeneous systems by use of different types of layered clays.
