    Abstract: 1463850 4 11 -Dioxy-4-oxo-erythromycin B derivatives ABBOTT LABORATORIES 19 June 1974 [21 June 1973] 27249/74 Heading C2C Novel compounds I and II in which R 5 is CH(R 7 )-SR 8 (where R 7 is hydrogen or C 1-6 alkyl and R 8 is C 1-6 alkyl) and R 6 is hydrogen or C 2-6 alkanoyl provided that when R 6 is hydrogen then R 5 is also hydrogen are prepared by reacting erythromycin B with a di-C 1-6 alkyl-sulphoxide and C 2-6 alkanoic acid anhydride to form a compound I (R 5 = CH(R 7 )-SR 8 and R 6 = C 2-6 alkanoyl) which is hydrolysed with an alkali metal bicarbonate to form a compound I (R 5 =CH(R 7 )-SR 8 and R 6 = hydrogen) which in the presence of HgO/ HgCl 2 forms a compound II which is hydrolysed by dil. HCl to compound I (R 5 = R 6 = hydrogen). Compound I (R 5 =R 6 =hydrogen) is also prepared by treating compound II with chloramine T.
