A method for synthesizing C-glycosides of ulosonic acids such as Neu5Ac, by which diastereocontrolled synthesis of .alpha.-C-glycosides of ulosonic acids is attained, is disclosed. In the method of the present invention, an ulosonic acid sulfone or phosphite is reacted with an aldehyde or ketone compound in the presence of a lanthanide metal halide.
L'invention concerne un procédé de synthèse de C-glycosides d'acides ulosoniques tel que Neu5Ac permettant la synthèse diastéréoréglée d'.alpha.-C-glycosides d'acides ulosoniques. Le procédé de la présente invention consiste à faire réagir un sulfone ou un phosphite d'acide ulosonique avec un composé aldéhyde ou cétone en présence d'un halogénure métallique de lanthanides.
