摘要:
The present invention relates to a new method of protection of the carboxy group in the chemistry of the compounds of .beta.-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.In particular, if the .beta.-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.
