The synthetic methods for such chiral C3 synthons as optically active glycerol and derivatives, which are widely used in asymmetric synthesis, were reviewed with 24 references.
Optically pure silicon containing amino acids are unnatural amino acids synthons and have broad applications in the synthesis of many drugs, plant protectants and fine chemicals.
