    摘要: A new, efficient process is provided for the production of 7.beta.-[(2D-2-amino-2-carboxy)-ethylthio-acetamido]-7.alpha.-methoxy-3-[(1-methyl-1H-tetrazole-5-yl) thiomethyl]-3-cephem-4-carboxylic acid useful as new antibacterial agent. This process is economic in using as the starting material the inexpensive, corresponding cephem compound containing no 7.alpha.-methoxy group on the cephem nucleus and comprises 7.alpha.-methoxylation of a protected derivative of the starting cephem compound with t-butyl hypochlorite and lithium methoxide, followed by inactivation of the excessive methoxylation reagents with a trialkyl phosphite and acetic acid to prevent undesired side-reactions such as oxidation of the alkylthioacetyl group of the product, and further by conventional removal of the protecting groups.

    摘要: A 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is now synthetized, which is a new compound useful in that this new 9-O-alkanoyl-3"-O-alkanoyloxymethyl derivative of the SF-837 substance exhibits an antibacterial activity comparable to that of the parent SF-837 substance but is advantageously free from the unpleasant bitter taste inherent to the SF-837 substance and is hence adapted for oral administration. A process of producing the 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is also provided, which comprises hydrolysing partially and selectively a 9,2'-di-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance in an aqueous alkanol or aqueous acetone. The 9,2'-di-O-alkanoyl-3"-O-alkanopyloxymethyl-SF-837 substance may be prepared by reacting a 9,2'-di-alkanoyl- or O-mono-O-alkanoyl-3"-O-thiomethoxymethyl-SF-837 substance with an alkanoic anhydride which is exemplified by acetic anhydride or propionic anhydride in the specification.
