    摘要: A process for the preparation of optically active or racemic lactone diol derivatives of the formula ##STR1## (for use as intermediates in the Corey prostaglandin synthesis). Optically active or racemic lactone diol derivatives are inclosed, in whichR.sup.3 and R.sup.4 are the same or different and stand for a hydrogen, or a lower alkanoyl optionally substituted with one, two or three halogen atoms, or form together a ##STR2## group, in which R.sup.5 and R.sup.6 are the same or different and stand for a hydrogen, alkyl or aryl, with a process for preparing them.According to the invention the above compound are prepared by reacting optically active or racemic lactone of the formula II with formaldehyde or with a formaldehyde polymerisate, in the presence of the mixture of a strong acid and water or of a lower alkane carboxylic acid optionally substituted with one, two or three halogen atoms, and then optionally subjecting the obtained compound of the general formula I, in which R.sup.3 and/or R.sup.4 stand for an alkanoyl optionally substituted with one, two or three halogen atoms to partial or total hydrolysis or alcoholysis in an acid or alkaline medium and/or reacting it with the oxo-compounds of the formula R.sup.5 --CHO or R.sup.6 --CO--R.sup.5 or with the acetals of the above compounds.The compounds according to the invention are useful intermediates in the Corey prostaglandine synthesis.
