Definitions
- the present invention relates to a gentle process for catalytic hydrogenation and a process for the production of biotin using the hydrogenation step.
- European patent EP-B-0 273 270 describes a biotin synthesis in which hydrogenation takes place according to equation I.
- Isopropanol is preferably used as the solvent here.
- Ri is a phenylethyl group
- R 2 is hydrogen, acetyl, propionyl, benzoyl, benzyl, ethoxycarbonyl, tert-butoxycarbonyl, benzyloxycarbonyl, phenoxycarbonyl, p-methoxybenzyl, methoxymethyl, pyranyl, benzeneslfonyl -, p-Toluenesulfonyl-, methylsulfonyl, diphenylphosphinyl, diethoxyphosphinyl, - trimethylsilyl, or a butyldimethylsilyl radical and R 3 is selected from H and C ⁇ . 4 alkyl.
- the European patent application EP-A-0 633 263 describes the hydrogenation with a soluble Pd catalyst, preferably dichlorobis (benzonitrile) palladium or palladium acetate in a solvent mixture of water and at least one alcohol.
- a soluble Pd catalyst preferably dichlorobis (benzonitrile) palladium or palladium acetate in a solvent mixture of water and at least one alcohol.
- the hydrogenation is carried out with palladium acetate in isopropanol.
- the European patent application EP-A-0 780 392 is concerned with the problem of separating such soluble catalysts from the reaction mixture. After the reaction has been carried out, it is proposed to add a polymeric flocculant which precipitates the catalyst out of the solution and filters off the precipitate.
- a first object of the present invention is accordingly a process for the catalytic hydrogenation of at least one C-C double bond in a compound having at least one basic saltable functional group, in which the hydrogenation is carried out in a protic solvent at a pH> 7.
- the double bond is preferably located on a thiazole ring system.
- a thiazole ring system is understood to mean a ring system comprising one or more, preferably fused rings, which contains at least one nitrogen heteroatom and at least one sulfur heteroatom.
- the rings can be saturated or unsaturated.
- the at least one double bond to be hydrogenated can be one or more double bonds in the ring system and / or one or more double bonds directly adjacent to rings in the system.
