Abstract: Provided in the present invention is a method for preparing chiral alkyl compounds by the asymmetric hydrogenation reaction of iron complex catalysts catalysing olefins: using the disubstituted olefin shown in formula I as a raw material, atmospheric hydrogen as a hydrogen source, FeX2-8-OIQ complex as a catalyst, and a silane compound and acetonitrile as cocatalysts, and reacting for 12-24 hours under the action of a reducing agent to prepare the chiral alkyl compound shown in formula II. The method of the present invention has mild reaction conditions, simple operation, and high atom economy. In addition, the reaction does not require the addition of any other toxic transition metal (such as ruthenium, rhodium, and palladium), and has great practical application value in the synthesis of drugs and materials. The conversion rate of the reaction is also good, generally reaching >99%, and the enantioselectivity is also high, generally 70-99%.
Abstract: The present invention provides compounds, compositions thereof, and methods of using the same for the inhibition of HPK1, and the treatment of HPK1-mediated disorders.
