Amidation of unprotected aminoacids has been investigated using a variety of ‘classical“ coupling reagents, stoichiometric or catalytic group(IV) metal salts, and boron Lewis acids. The scope of the reaction was explored through the attempted synthesis of amides derived from twenty natural, and several unnatural, aminoacids, as well as a wide selection of primary and secondary amines. The study also

Doubling up: The direct bio‐inspired dimerization of commercially available amine‐free tryptophanderivatives in aqueousacidicmedia provides C2‐symmetrical and nonsymmetrical dimeric compounds. Further processing completes the concise syntheses of naturally occurring dimeric diketopiperazine alkaloids such as (+)‐WIN 64821 (see picture) in overall yields of up to 20 %.
The invention relates to compounds that have an affinity to the μ-opioid receptor and the ORL 1-receptor, methods for their production, medications containing these compounds and the use of these compounds for the treatment of pain or other conditions.
