WebThe chiral pool is a "collection of abundant enantiopure building blocks provided by nature" used in synthesis. [1] [2] In other words, a chiral pool would be a large quantity of common organic enantiomers. Contributors to the chiral pool are amino acids, sugars, and terpenes. Their use improves the efficiency of total synthesis. WebJul 3, 2024 · Use of chiral solvents in asymmetric synthesis as a sole source of enantioselection remains largely unexplored in organic synthesis. We found that the use of a helical macromolecular catalyst of wh...
