Asymmetric synthesis method of optically active β-hydroxy-α-substituted carboxylic acid ester |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for asymmetrically synthesizing an optically active β-hydroxy-α-substituted carboxylic acid ester having high diastereoselectivity and enantioselectivity, which has been difficult so far. An aldehyde compound is reacted with an aminosilyl enol ether compound or an α-alkoxyketene silyl acetal compound in the presence of a chiral zirconium catalyst to form an optically active β-hydroxy-α-amino acid ester or an optically active α-amino acid ester. , Β-dihydroxycarboxylic acid ester.
