Asymmetric epoxidation is a green route to enantiopure epoxides, but often suffers from low enantioselectivity toward unconjugated terminal alkenes. Mining of the NCBI non-redundant protein sequences with a reconstructed ancestral sequence based on six st

The invention relates to a method for preparing chiral gamma-amino alcohol and chiral alpha-allyl alcohol by a one-pot method. The method comprises the following steps: making a racemic alpha-allyl alcohol compound, an amine compound, a chiral ruthenium complex and an alkaline reagent react in an organic solvent, and carrying out separation and purification after completion of the reaction, so that chiral gamma-aminoalcohols and chiral alpha-allylalcohol are prepared, wherein a chiral ruthenium complex is selected from one of them. According to the preparation method of the chiral compound, two chiral compounds with wide purposes, namely the chiral gamma-amino alcohol and the chiral alpha-allyl alcohol, are obtained at the same time through a one-pot reaction, the reaction is simple, the atom economy is high, few by-products are produced, and the requirements of green chemistry are met.

Enantioselective vinylation of aldehydes via direct catalytic asymmetric Grignard reaction of aldehdyes and the vinyl Grinard reagent is a long-standing challenge. This work demonstrated that the magnesium (S)-3,3′-dimethyl BINOLate enantioselectively catalyze the direct vinylation of aldehydes with the deactivated vinylmagnesium bromide by bis(2-[N,N′-dimethylamino]ethyl) ether (BDMAEE) in the addition of n-butylmagnesium chloride. The highest ee of 63% was achieved up to date.
