权利人:OGO SEIJI; FUKUZUMI SHUN-ICHI; JAPAN SCIENCE & TECH AGENCY
摘要:An object of the present invention is to provide a method for synthesis of keto acids by hydration of an acetylene compound (acetylene-carboxylic acids) under mild conditions free from harmful mercury catalysts and a method for synthesis of amino acids from acetylene-carboxylic acids in a single container (one-pot or tandem synthesis). In one embodiment of the method according to the present invention for synthesis of keto acids, acetylene-carboxylic acids is hydrated in the presence of a metal salt represented by General Formula (1), n nwhere M 1 represents an element in Group VIII, IX, or X of the periodic table, and X 1 , X 2 , or X 3 ligand represents halogen, H 2 O, or a solvent molecule, and k represents a valence of a cation species, and Y represents an anion species, and L represents a valence of the anion species, and each of K and L independently represents 1 or 2, and k×m=L×n.

标题 :Process and intermediates for the synthesis of Vitamin D3 metabolites and chenodeoxycholic acid
发明人：BATCHO ANDREW D; USKOKOVIC MILAN R; WOVKULICH PETER M
权利人:HOFFMANN LA ROCHE
摘要:The present disclosure is directed to a process for the synthesis of chenodeoxychloic acid, 25-hydroxycholesterol and 1α,25-dihydroxycholesterol from 17-keto steroids. A cholic acid side chain is stereospecifically introduced by reaction of the appropriate 17-keto steroid with ethyltriphenylphosphonium halides to produce the 17-ethylidene derivative which is allowed to react with acrylic acid esters or propiolic acid esters followed by hydrogenation.
