Relevant academic research and scientific papers

Synthetic studies towards the synthesis of western and eastern chloropeptin I, II subunits

The western subunit (16-membered ring) was synthesized by the intramolecular SNAr reaction while the first 16-membered ring compound was obtained as a model of the eastern subunit via an intramolecular Ni0 mediated coupling reaction.

Synthesis of a model of chloropeptins I, II western subunit by the intramolecular S(N)Ar based methodology

Formation of a biaryl ether bond between the termini of a tetrapeptide containing a highly racemization prone amino acid by the intramolecular SNAr reaction afforded two diastereomeric 16-membered macrocycles along with their respective atropoisomers. The (R,S,R) and its atropoisomer constituted model of chloropeptins I, II, western part.
