Abstract:
LACTONES OF 2-(CARBONYL-AMINO-METHYL)-5-HYDROXYMETHYL-3,6-DIHYDRO-2H-1,3-THIAZINE-4 -CARBOXYLIC ACIDS USEFUL AS INTERMEDIATES FOR ANTIBIOTICS OF THE C-CEPHALOSPORINE FAMILY AND THEIR PREPARATION. THE INVENTION RELATES TO NOVEL DIHYDRO-1,3-THIAZINE COMPOUNDS OF THE FORMULA
2-(R-OOC-CH(-Y)-),7-(O=)-1,2,5,7-TETRAHYDRO-4H-FURO(3,4-D)
(3,1)THIAZINE
WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL AND ARALKYL, Y IS SELECTED FROM THE GROUP CONSISTING OF -HN-AC, PHTHALIMIDO AND-NH-R'',R'' IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL AND ARALKYL AND AC IS THE ACYL RADICAL OF AN ORGANIC CARBOXYLIC ACID OF 1 TO 18 CARBON ATOMS AND TO A NOVEL PROCESS FOR THE PREPARATION OF THE SAID COMPOUNDS.
