    摘要: A method for preparing a propargylic alcohol catalyzed by 2-morpholinoisobornane-10-thiol (MITH) is disclosed, which includes reacting R1CHO with R2CCH in the presence of R3ZnR4 and MITH, wherein each of R1, R2, R3, and R4, independently, is optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, alkylsilyl, heterocycloalkyl, heterocycloalkenyl, aryl, aryloxy, or heteroaryl. The method can give enantioenriched propargylic alcohols with good enantioselective at low loading of MITH.

    摘要: The present invention proposes a chiral diene ligand, a fabrication method thereof and applications thereof. The chiral diene ligand is a bicyclo[2.2.1] diene ligand having structural specificity and high stability, which favors the bicyclo[2.2.1] diene ligand to take part in asymmetric transformations, particularly an asymmetric addition reaction involving a metal catalyst in a basic environment. Most of the products of the reactions implemented by the chiral diene ligands of the present invention have superior optical activity. The method of the present invention comprises a first oxidation step, a saponification step, a second oxidation step, a deprotonation step, and a cross-coupling step. The chiral diene ligand of the present invention is very suitable to be used in the fabrication or synthesis of various chemicals and medical products.
