Preparation of P-chirogenic phospholanes and their use in asymmetric synthesis
摘要:
Materials and methods for preparing P-chirogenic monophospholanes and bisphospholanes are disclosed. The methods employ stereoselective cyclization to generate the phospholane rings followed by pyramidal inversion to access a variety of P-chirogenic phospholanes. When bound to transition metals such as rhodium, the disclosed P-chirogenic phospholanes may be used as catalysts in asymmetric synthesis of valuable pharmaceutical chemical entities, including pregabalin.
