Abstract
The process comprises reaction of a 2-acetamido-2-desoxy-3-O-sulphonyl substd. hexapyranoxide of formula (II) (where R7 = various radicals and R1,2,4,5 = various types of radicals) with an alkali metal azide in a solvent or mixt. of inert solvents in the presence of a tetraalkyl ammonium salt. Subsequent catalytic redn. and reaction with a deriv. of alpha-halocarboxylic acid of formula X-CHR3-CO2R4 (III), (where X = halogen R3 = H or lower alkyl) yields derivs. of muramic acid of formula (I).
