COMPOSITIONS OF AND METHODS FOR PRODUCING PHOSPHORUS-CHIRAL MONOMERS AND OLIGOMERS

摘要

Described herein are phosphorus-containing monomers and oligomers and methods for making such monomers and oligomers. Each subunit of the oligomers may be the same or different. Furthermore, the phosphorus atom in the monomers and at least two of the phosphorus atoms in the oligomers are chiral, that is, attached to four different chemical groups in a desired configuration. The methods described herein, which use an intramolecular catalyst, permit the synthesis of oligomers in which each chiral phosphorus center is in a desired stereochemical configuration.
