    • In accordance with this invention, it has been found that carbon and oxygen analogs of 6.beta.-aminopenicillanic acid and biologically active derivatives thereof can be formed from esters of 6-oxopenicillanic acid. For example, 6.beta.-phenoxyacetoxypenicillanic acid--an oxygen analog of penicillin V and 6.beta.-phenoxyacetylmethylpenicillanic acid--a carbon analog of penicillin V, may be formed from an ester of 6-oxopenicillanate. The ester of 6-oxopenicillanic acid is formed by a diiospropyl carbodiimide/dimethyl sulfoxide oxidation of the corresponding ester of 6.alpha.-hydroxypenicillanic acid. The oxygen analogs are formed by reducing the ester of 6-oxopenicillanic acid to the corresponding 6.beta.-hydroxypenicillanate and then forming the desired analog by acylation. The carbon analogs are formed by a Wittig reaction of the ester of 6-oxopenicillanic acid with a suitable acylmethylenetriphenylphosphorane followed by saturation of the newly formed double bond and removal of the protective ester group.
    • 根据本发明,已经发现6β-氨基青霉烷酸的碳和氧类似物及其生物活性衍生物可以由6-氧代青霉烷酸的酯形成。 例如,可以由6-氧代青霉烷酸酯形成6β-苯氧基乙酰氧基青霉烷酸 - 青霉素V的氧类似物和6β-苯氧基乙酰基甲基青霉烷酸 - 青霉素V的碳类似物。 6-氧代青霉烷酸的酯由6α-羟基青霉烷酸的相应酯的二亚丙基碳二亚胺/二甲基亚砜氧化形成。 通过将6-氧代青霉烷酸的酯还原成相应的6β-羟基青霉烷酸形成氧类似物,然后通过酰化形成所需的类似物。 碳类似物通过6-氧代青霉烷酸的酯与合适的酰基亚甲基三苯基正膦的维蒂希反应形成,接着饱和新形成的双键并除去保护酯基。
