| abstract | i) l'on fait réagir l'acide glyoxylique sur de la cyclohexanone en présence d'unnacide halogéné afin d'obtenir un brut de réaction B1, puis ii) l'on fait réagir ce brut de réaction B1 après solubilisation dans un solvantnorganique en présence d'un acide fort soluble dans ledit solvant organique ounde résines fortement acides afin d'obtenir l'énol-lactone de l'acide 2-oxocyclohexylidèneacétiquenque l'on isole si désiré, net application à la préparation de la 2-coumaranone.Process for the preparation of the enol-lactone of 2-oxocyclohexylideneacetic acid in which i) reacting glyoxylic acid on cyclohexanone in the presence of a halogenated acid in order to obtain a crude reaction B1, then ii) reacting this crude reaction B1 after solubilization in an organic solvent in the presence of a strong acid soluble in said organic solvent or strongly acid resins in order to obtain the enol-lactone of acid 2- oxocyclohexylideneacetic which is isolated if desired, and application to the preparation of 2-coumaranone. |
