Method of protection of the carboxy groups in the chemistry of β-lactam compounds |
abstract |
The present invention relates to a new method of protection of the carboxy group in the chemistry of the compounds of β-lactam type. According to such a method, the carboxy group is protected by being transformed into its corresponding phenyl-acetoxy-methyl ester, which is then removed by an enzymatic route by means of penicillinacylase. n In particular, if the β-lactam compound also bears a phenyl-acetamidic substitutent, this latter is simultaneously hydrolysed during the same step of removal of the carboxy function protecting group. |
