Compounds of formula I ##STR1## wherein R represents hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.5 -C.sub.7 cycloalkyl, methylene-dioxy or phenyl, which may be substituted by one or two groups independently selected from hydroxy, halogen, nitro, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy; R.sub.1 and R.sub.2 independently represent hydrogen, COOR.sub.3, --CONR.sub.4 R.sub.5, ##STR2## --OCONR.sub.4 R.sub.5, --OCOR.sub.3, --NR.sub.4 R.sub.5, --OCOOR.sub.6, --NR.sub.3 COR.sub.7, --NR.sub.CONR.sub.4 R.sub.5, --N.dbd.CH--NR.sub.4 R.sub.5, NO.sub.2, CN, OH, SR.sub.3, wherein R.sub.3 is hydrogen or C.sub.1 -C.sub.6 alkyl, R.sub.4 and R.sub.5 independently are hydrogen or C.sub.1 -C.sub.6 alkyl, R.sub.6 is C.sub.1 -C.sub.6 alkyl, and R.sub.7 is hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy, with the proviso that R.sub.1 and R.sub.2 cannot be hydrogen at the same time; X is oxygen or sulphur; Y represents a C.sub.2 -C.sub.6 alkylene chain or a C.sub.5 -C.sub.7 cycloalkylene group; and their pharmaceutically acceptable salts are provided and their use in pharmaceutical compositions which may be used in the treatment of cardiovascular diseases.

Benzoxazinone and benzothiazinone derivatives having cardiovascular

Intermediates for transforming (2S,3S)-2-amino-3-phenyl-1,3-propanediols into their (2R,3R)-enantiomers are described. The final compounds are useful intermediates for the synthesis of antibiotics like chloramphenicol, Thiamphenicol and Florfenicol.

Process for the stereochemical inversion of

Intermediates for the stereochemical inversion of

A four step process for transforming (2S,3S)-2-amino-3-phenyl-1,3-propanediols into their (2R,3R)-enantiomers is described. The final compounds are useful intermediates for the synthesis of antibiotics like Chloramphenicol, Thiamphenicol and Florfenicol. The starting products generally are discard products in the synthesis of said antibiotics.
