    • Disclosed is a novel method for the manufacture of biotine (+) having formula (I) in which a furoimidazol derivative having general formula (II) is acylated in position N-3, the acylated compound is made to react with an S donor giving a thienoimidazol, the acyl group is removed in position N-3, the side chain is introduced by means of a Grignard reactant, and after elimination of the hydroxy group, hydrogenation of the unsaturated compound obtained and separation of protective groups in position N-1 the end product biotine (+) is obtained. Biotine (+) is an essential vitamin and is used inter alia in the pharmaceutical sector.
