Patent GB-863420-A (GB)
Title: Preparation of tetracycline, 4-epitetracycline and 5ª-epitetracycline
Filed: 1958-03-17
Abstract: Tetracycline or 5a-epitetracycline are produced by reducing a 5a(11a)-dehydrotetracycline having the formula:  <FORM:0863420/IV (b)/1> wherein Z is hydrogen, chlorine or bromine, with hydrogen in the presence of a hydrogenation catalyst e.g. a finely divided noble metal catalyst such as metallic palladium, until 2 moles of hydrogen have been absorbed per mole of 5a(11a)-dehydrotetracycline.  The 5a (11a)-dehydrotetracyclines are produced by the process described and claimed in Specification 863,419.  The 4-epimer of 5a(11a)-dehydrotetracyclines of the p  above formula may also be reduced when the resulting product is 4-epitetracycline.  The reaction is carried out at temperatures of 0 to 100 DEG C. and pressures of 1/2 to 100 atmospheres in the presence of a polar solvent such as aliphatic alcohols such as ethanol and n-butanol, alkoxy alkanols such as 2-methoxy ethanol and 2-ethoxyethanol and mixtures thereof with said alkanols, and especially dimethylformamide.  To recover the tetracycline, the catalyst is filtered off, the solution concentrated in vacuo, the residue dissolved in water or alcohol and seeded with tetracycline to precipitate the tetracycline.  The 5a-epitetracycline remains behind in the mother liquor and is separated therefrom by column chromatography e.g. by passing down a column of "belite" buffered with 0,1 hydrochloric acid and developed with an acidified 20% chloroform, 80% butanol.  The eluate is concentrated to remove the solvents, the residue freeze dried, dissolved in butanol, adjusted to pH 1,5 with hydrochloric acid and ether added to precipitate 5aepitetracycline hydrochloride.  5a-epitetricycline has low antibiotic activity and may be converted to anhydrotetracycline by the acid degradation process of Specification 744,020. Specifications 747,779 and 775,115 also are referred to.
