    摘要:The invention provides a novel process, novel process steps and novel intermediates useful in the synthesis of pharmaceutically active compounds, especially KRAS G12C inhibitors. The present invention provides a direct enantioselective chemical manufacturing method of making Compound A, or a pharmaceutically acceptable hydrate or solvent thereof: (I). The invention provides a process for preparing Intermediate B6* comprising reacting Intermediate B4* with Intermediate B5* in an atroposelective coupling reaction, using a chiral catalyst.

    摘要:A method of producing a monomer of a Shiga toxin B-subunit (STxB) protein or of a variant thereof by peptide chemical synthesis, as well as to a method of producing a pentamer of the STxB protein or of the variant thereof. The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.
