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.
该发明的一个方面涉及手性双恶唑啉及其在不对称催化中的应用。这种手性双恶唑啉是一种新型化合物类,预计将在多个领域得到应用,例如在不对称合成中。例如,一种双恶唑啉配体使得对一系列芳香族和脂肪族醛的催化不对称炔基化和烷基化成为可能,产生高产率和对映选择性的手性丙炔醇和二级醇。
