Chiral pool synthesis is a
strategy that aims to improve the efficiency of enantioselective synthesis. It
starts the organic synthesis of a complex enantiopure chemical compound from a
stock of readily available enantiopure substances. Common chiral starting
materials include monosaccharides and amino acids. The built-in chirality is
then preserved in the remainder of the reaction sequence.
This strategy is especially
helpful if the desired molecule bears a great resemblance to cheap enantiopure
natural products. Otherwise, a long, tortuous synthesis involving many steps
with attendant losses in yield may be required. At times, it may be difficult
to find a suitable enantiopure starting material; other techniques may prove
more fruitful.
