chiral phase-transfer catalysts - Opis:
- Phase-transfer catalysis (PTC) has been already known for 60 years and has an established position both on a laboratory and industrial scale. It is an energy-saving technique, ensuring high yields and selectivity under mild conditions. PTC is successfully used, among others, in the pharmaceutical, polymer, agrochemical industries, for the production of dyes, fragrances and flavors, to name a few. Currently, the development of phase-transfer catalysis is focused mainly on the search for active catalysts as well as extending the scope of its applications. In particular, catalysts immobilized on an insoluble carrier, which can be easily separated from the reaction mixture and recycled many times, are of great interest. The growing demand for chiral compounds has resulted in the development of phase-transfer catalysts which, while retaining the advantages of conventional PTC, will allow to obtain a product with high enantiomeric excess. This work characterizes the phase-transfer catalysis and presents examples of its applications in organic synthesis.
