摘要: NEW MATERIAL:A compound shown by the formula I (M is alkali metal; R is alkyl; R is alkyl which may be replaced with halogen or aryl which may be replaced with halogen, trihalogenomethyl or alkyl). EXAMPLE:Sodium hydride bis(2-methoxyethoxy)(hexafluoroisopropoxy)aluminum. USE:A reducing agent especially useful for reducing carbonyl group to give stereospecific hydroxyl group, for example, it is used for reducing carbonyl group at the 15-position in prostaglandin synthesis. PREPARATION:A compound shown by the formula II is reacted with a compound shown by the formula R -OH in a ratio of the latter to the former of usually 0.5-1.5mol to 1mol preferably in a solvent approximately at 0 deg.C.

摘要: PURPOSE:To advantageously produce a stereospecific hydroxyl groupcontaining compound by reducing a carbonyl group of a carbonyl group-containing compound by using a specific reducing agent having stereospecificity. CONSTITUTION:In obtaining a compound of formula III (e.g. compound of formula IV) by reducing a compound of formula I [R is OH-protecting group; R is alkyl, alkenyl, aryl, etc.; X is group of formula II (Y is carbonyl-protecting group), etc.], a reducing agent having stereospecificity is used. A compound of formula V [M is Na or Li; R is alkyl; R is alkyl or phenyl (may be replaced with halogen, trihalogenomethyl or alkyl)], especially a compound wherein M is Na, R is methyl or ethyl and R is ethyl, n-propyl, 2-fluoroethyl, phenyl, naphthyl, etc., is preferable as the reducing agent. This reducing agent of formula V is obtained by bringing a compound of formula VI into contact with a compound of formula VII.
