Synthetic studies towards western and eastern macropolypeptide subunits of kistamycin
摘要:
The western subunit (fused bicyclic 16+15 membered ring) was synthesized by sequential intramolecular SNAr reaction and the first 17-membered ring compound as model of the eastern subunit was obtained by an intramolecular Ni-0 mediated coupling reaction.
