The present invention encompasses compounds of the formula ##SPC1## Wherein R.sub.1 is lower alkyl containing 1-7 carbon atoms, phenyl, halo(substituted)phenyl, phenyl, or lower alkoxy (substituted)phenyl containing 1-7 carbon atoms; R.sub.2 and R.sub.3 are lower alkyl containing 1-7 carbon atoms; and R.sub.4 is hydrogen or lower alkyl containing 1-7 carbon atoms. The compounds of the present invention are prepared by the condensation of alkyl(4-formylphenoxy)-2,2-dialkyl acetate with an appropriate alkyl or aryl methyl/ketone in base. These compounds have antibiotic activity and in particular they are antifungal agents effective against Trichophyton mentagrophytes. Halophenyl members of the present invention are also effective hypolipemic agents.
本发明涵盖了如下式的化合物:##SPC1## 其中R.sub.1是含1-7个碳原子的低烷基、苯基、卤素(取代)苯基、苯基或含1-7个碳原子的低烷氧基(取代)苯基;R.sub.2和R.sub.3是含1-7个碳原子的低烷基;R.sub.4是氢或含1-7个碳原子的低烷基。本发明的化合物是通过低烷基(4-甲酰基苯氧基)-2,2-二烷基乙酸酯与适当的低烷基或芳基甲基/酮在碱性条件下缩合制备而成。这些化合物具有抗生素活性,特别是它们是对Trichophyton mentagrophytes有效的抗真菌剂。本发明的卤素苯基成员也是有效的降脂药物。
