4-halogeno-2-oxyimino-3-oxobutyric acids and derivatives |
| abstract |
A method of producing a 4-halo-2-(substituted or unsubstituted)hydroxyimino-3-oxobutyric acid ester or amide, which is a synthetic intermediate of value for the production of cephalosporins containing an aminothiazole group, characterized by reacting a 2-(substituted or unsubstituted)-hydroxyimino-3-oxobutyric acid or an ester or amide thereof with a silylating agent and reacting the resulting novel 2-(substituted)hydroxyimino-3-silyloxy-3-butenoic acid ester or amide with a halogenating agent. |
