Definitions

  • the present invention relates to acyl derivatives of erythromycin oxime and to the preparation thereof.
  • acylation of erythrornycin with different acid chlorides or acid anhydrides yields a variety of products with a single acyl grouping attached to the hydroxyl group of the desosaminyl moiety.
  • the sole exception is with the use of acetic anhydride as an acylating agent, which yield erythromycin diacetate.
  • EXAMPLE 2 Erythromycin oxime mono-palmitate Erythromycin oxime mono-stearate From 5 g. (6.67 millimols) of erythromycin oxime, 2.616 g. (8.64 millimols) of stearoyl chloride and 2.5 g. of sodium bicarbonate, by the process described in Example 1, there are obtained 5.24 g. (77.49%) of mono-stearate, M.P. 74-78 C.
  • EXAMPLE 4 Erythromycin oxime mono-benz oate From 5 g. (6.67 millimols) of erythromycin oxime, 1.26 g. (8.64 millimols) of benzoyl chloride and 2.5 g. of sodium carbonate, by the process described in Example 1, there are obtained 4.15 g. (73%) of monobenzoate, M.P. ISO-152 C.
  • EXAMPLE 6 Erythromycin oxime mono-ethylsuccinate From 5 g. (6.67 millimols) of erythromycin oxime, 1.098 g. (6.67 millimols) of succinic acid ethylester chloride and 2.5 g. of sodium bicarbonate, by the process described in Example 1, there are obtained 4.23 g. (72.5%) of mono-ethylsuccinate, M.P. 99102. C.
  • EXAMPLE 7 Erythromycin oxime mono-methyladipate From 5 g. (6.67 millimols) of erythromycin oxime, 1.19 g. (6.67 millimols) of adipic acid methylester chloride and 2.5 g. of sodium bicarbonate, by the process described in Example 1, there are obtained 4.5 g. (76%) of mono-methyladipate, M.P. 89-94 C.
  • EXAMPLE 8 Erythromycin oxime mono-ethyladipate From 5 g. (6.67 millimols) of erythromycin oxime, 1.28 g. (6.67 millimols) of adipic acid mono-ethylester chloride and 2.5 g. of sodium bicarbonate, by the process described in Example 1, there are obtained 4.8 g. (79.3%) of mono-ethyladipate, M.P. 82-86 C.
  • EXAMPLE 9 Erythromycin oxime bis-propionate To a suspension of 5 g. (6.67 millimols) of erythromycin oxime in ml. of dry acetone, 5.0 g. of dry sodium bicarbonate were added. Then the solution of 1.596 g. (17.29 millimols) of propionyl chloride in 50 ml. of dry acetone was added dropwise with stirring over a period of one hour. Stirring was continued for 8 hours more While heating the reaction mixture under reflux. After cooling to room temperature and filtration, the clear filtrate was diluted with a solution of 5 g. sodium bicarbonate in 250 ml. water and extracted with one 100 m1. and two 50 ml. portions of ether. The isolation of the product was performed in the same manner as described in Example 1. The yield was 4.49 g. (78.2%), M.P. 196-202 C.

  • EXAMPLE 13 Erythromycin oxime bis-methylsuccinate From 5 g. (6.67 millimols) of erythromycin oxime, 2.424 g. (16.1 millimols) of succinic acid methylester chloride, and 5 g. of sodium bicarbonate, by the process described in Example 9, there are obtained 5.18 g. (79.5%) of bis-methylsuccinate, M.P. 173176 C.
  • EXAMPLE 14 Erythromycin oxime bis-ethylsuccinate From 5 g. (6.67 millimols) of erythromycin oxime, 2.649 g. (16.1 millimols) of succinic acid ethylester chloride and 5 g. of sodium in carbonate, by the process described in Example 9, there are obtained 4.92 g. (73.4%) of bis-ethylsuccinate, M.P. -162 C.
  • EXAMPLE 15 Erythromycin oxime bis-methyladi'pate From g. (6.67 millirnols) of erythromycin oxime, 2.86 g.
