C07D501/22 - CPC Classification

Classification description:

Heterocyclic compounds containing 5-thia-1-azabicyclo [4.2.0] octane ring systems, i.e. compounds containing a ring system of the formula:, e.g. cephalosporins; Such ring systems being further condensed, e.g. 2,3-condensed with an oxygen-, nitrogen- or sulfur-containing hetero ring; Compounds having a nitrogen atom directly attached in position 7 with a double bond between positions 2 and 3 7-Acylaminocephalosporanic or substituted 7-acylaminocephalosporanic acids in which the acyl radicals are derived from carboxylic acids with radicals containing only hydrogen and carbon atoms, attached in position 3
