Enantioselective synthesis on the solid phase

Organic transformations on substrates which are immobilized on an insoluble, polymeric carrier have found broad application in compound collection synthesis. In contrast to other synthetic methodologies in solid-phase organic synthesis, reactions that afford non-racemic products are strikingly under-represented. Not only does the introduction of stereoinformation on immobilized, achiral starting materials provide enantioenriched products which can be of value for biological testing, but it also opens up new perspectives for accessible structures. This feature article gives an overview of successful enantioselective transformations on a solid support. Critical differences in the corresponding solution-phase protocols are highlighted, and applications to the generation of compound collections are particularly mentioned.
