  • Publication number: 20240093250
    Abstract: The present invention relates to processes for preparing linkers that are useful in the conjugation of therapeutic molecules (e.g., cytotoxic agents) with targeting moieties (e.g., proteins, peptides, antibodies, nanoparticles, nucleic acids). During said processes lipases like lipase B from Candida antarctica were used for enantioselective resolution of (S,S)-2-benzylthiocyclohexanol or (S,S)-2-benzylthiocycloheptanol in presence of acylating agent which are reduced for deprotection to yield (S,S)-2-mercaptocyclohexanol or (S,S)-2-mercaptocyclopentanol which can then be used for linking therapeutic with targeting moieties.
