权利人:SIGNA CHEMISTRY LLC; UNIV MICHIGAN STATE; LEFENFELD MICHAEL; DYE JAMES L; NANDI PARTHA; JACKSON JAMES
摘要:Alkali metal phosphides are useful intermediates for the synthesis of a variety of phosphine derivatives. Many of these phosphine derivatives are important industrial compounds with applications as synthetic intermediates or as ligands in a variety of homogeneous and heterogeneous synthetic processes. Alkali metal diarylphosphides in particular have been used in the synthesis of many phosphine ligands of importance. The invention relates to methods for generating and using alkali metal phosphides by reduction of the phosphorus sigma bonds of tri-substituted phosphorus derivatives with Group I metal/porous oxide compositions. Formula (I).

标题 :Synthesis, structure and use of bisoxazolidines for asymmetric catalysis and synthesis
发明人:WOLF CHRISTIAN; LIU SHUANGLONG
权利人:UNIV GEORGETOWN
摘要:One aspect of the invention relates to chiral bisoxazolidines and their use in asymmetric catalysis. The chiral bisoxazolidines are a novel class of compounds that is expected to find multiple applications, for example, in asymmetric synthesis. For example, a bisoxazolidine ligand enabled the catalytic enantioselective alkynylation and alkylation of a range of aromatic and aliphatic aldehydes, generating chiral propargylic alcohols and secondary alcohols in high yields and enantiomeric excess.
