Abstract
1. A process for the preparation of clavulanic acid ethers of Formula-01 (I): ** (Formula-01) ** or a salt or ether thereof where R1 is a hydrogen atom or methyl group, R2 is a hydrogen atom or methyl group, and X is a group of Sub-Formula-02 (a), (b), (c) or (d): ** (Formula-02) ** where R3 is an atom hydrogen or a lower alkyl, aryl, aralkyl or substituted alkyl group and R4 is an amino group or carboxylic acid group; whose process comprises subjecting to the protective group removal reaction, a compound of Formula-03 (V): ** (Formula-03) ** or a salt or ether thereof where R1, R2 and R3 are as defined in Relating to Formula-01 (I) and X1 is a group of Sub-Formula-02 (a), (b), (c), or (d) in which the amino group or carboxyl group is protected.
