A compound of formula I wherein PROT is an amine protecting group and PROT' is hydrogen; or PROT and PROT' together with the nitrogen atom to which they are attached form a heterocyclic ring as an amine protecting group, and PROT" is a thiol protecting group, processes for its production, intermediates in their production and production of intermediates in stereoisomerically pure form, and their use for the production of pharmaceutically active compounds.
A process for the preparation of a compound of formula
in the form of a single stereoisomer, comprising deprotecting the amine group in an N-protected amino-hydroxy-cyclohexylsulfanyl-acetyl-mutilin of formula
wherein R is an amine protecting group in the form of a single stereoisomer,
and isolating a compound of formula I in the form of a single stereoisomer obtained from the reaction mixture; compounds obtainable by such processes, e.g. a compound of formula I in a crystalline form, or salts of a compound of formula I in crystalline form, and processes for the preparation of intermediates for the production of a compound of formula I.
Process for the preparation of a compound of formula I
in the form of a single stereoisomer in crystalline form, comprising deprotecting the amine group in a compound of formula IIa
or in a mixture of a compound of formula IIa with a compound of formula IIb
and isolating a compound of formula I from the reaction mixture; compounds and salts of compounds of formula I in crystalline form; pharmaceutical compositions comprising such salts; processes for the preparation of intermediates and intermediates in a process for the preparation of a compound of formula I.
