Cephalosporan derivatives and their preparation |
| abstract |
Cis, trans and cis-trans mixtures of DL 7-R-amino-desacetoxycephalosporan compounds of the formula wherein R is selected from the group consisting of hydrogen and trityl and R1 is selected from the group consisting of lower alkyl of 1 to 6 carbon atoms optionally substituted with at least one chlorine and aralkyl of 7 to 15 carbon atoms with the proviso when R is hydrogen, R1 is selected from the group consisting of tert.-butyl,benzyl and ethyl, processes for their preparation and novel intermediates produced therein. |
