WebJan 3, 2024 · Chiral auxiliaries, organo-, organometallic, and biocatalysis, as well as the chiral pool approach were also employed with the goal of obtaining chiral bioactive flavonoids with a high enantiomeric ratio. WebChiral auxiliaries are enantiomerically pure compounds derived mostly from inexpensive chiral natural sources (i.e. chiral pool, see Section 2.13.1).The use of a chiral auxiliary in asymmetric synthesis is referred to as second-generation (2G) asymmetric synthesis. In this approach, a stoichiometric chiral auxiliary is covalently attached to the substrate …
The chiral pool is a "collection of abundant enantiopure building blocks provided by nature" used in synthesis. 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. Not only does the chiral pool contribute a premade carbon skeleton, their chirality is usually preserved in the remainder of the reaction sequence.
