    摘要: A process for producing a 2-aralkyl-3-hydroxypropionic acid (or its ester), comprising the steps of: reacting a 3-hydroxy-2-methylene-3-arylpropionic acid ester, easily obtained by the reaction of an arylaldehyde with an acrylic acid ester, with an acid anhydride to form a 2-aralkylidene-3-acyloxypropionic acid ester; subjecting the same to hydrolysis or alcoholysis; and reducing the resulting 2-aralkylidene-3-hydroxypropionic acid or its ester. The reduction step may be conducted in the presence of a base.

    摘要: The present invention provides a simple and inexpensive method for producing &agr;-hydroxy-&bgr;-aminocarboxylic acids and their esters. An ester of an N-protected &agr;-amino acid ester is converted into a &bgr;-ketosulfoxide, which is then processed with an acid to give an &agr;-ketohemimercaptal. Next, this is acylated and then processed with a base to obtain an N-protected &agr;-acyloxy-&bgr;-amino-thioester, which is then saponified to obtain an intended compound. According to the method of the present invention, it is possible to produce &agr;-hydroxy-&bgr;-aminocarboxylic acid derivatives, which are intermediates in producing various HIV protease inhibitors, renin inhibitors and carcinostatics, from a-amino acids. The method comprises reduced reaction steps, the selectivity in the method to give the intended product is high, and the yield of the product obtained is high.
