Abstract
The invention comprises compounds of the general formula <FORM:0991571/C2/1> wherein one of R1 and R2 represents a chlorine atom and the other a methyl group and X represents an oxygen or sulphur atom, and the preparation thereof and of the compounds in which R1 and R2 both represent a chlorine atom or both represent a methyl group by reacting D-glucosamine with a compound of the general formula <FORM:0991571/C2/2> and subjecting the resulting compound to ring closure by heating in an anhydrous or aqueous organic acid or by treatment with a dilute aqueous, aqueous-alcoholic or alcoholic mineral acid. Reference has been directed by the Comptroller to Specification 924,985.
