wherein R³ is phenyl, substituted phenyl, cyclohexenyl, cyclohexadienyl or an optionally substituted 5- or 6-membered heterocyclic ring containing up to three hetero atoms selected from oxygen, sulphur or nitrogen, R⁴ is hydrogen or formamido, R⁵ is hydrogen, C1-6 alkyl, substituted alkyl, aryl or aralkyl, R⁶ and R⁷ are the same or different and represent hydrogen, C1-6 alkyl, substituted alkyl, halogen, amino, phenyl, substituted phenyl, hydroxy or C1-6 alkoxy or R⁶ and R⁷ form the residue of an optionally substituted 5- or 6-membered carbocyclic ring or a 5- or 6- membered heterocyclic ring containing up to three hetero atoms selected from oxygen, sulphur or nitrogen, and X represents
or tautomers thereof wherein R⁸ and R⁹ are the same or different and each represents hydroxy, or protected hydroxy.
The use of the compounds is disclosed together with processes for their preparation.
