Huge (14-, 21-, 28-, 35-, 56- and 70-membered ring) macrocyclic lactams––a novel family of carbopeptoid-cyclodextrins
摘要:
Hydrogenation of linear omega-azido-pentafluorophenyl esters gives cyclic peptides containing 14-, 21-, 28-, 35-, 56- and 70-membered ring lactams from oligomers derived from epsilon-amino acids in excellent to moderate yields with a lack of racemisation during the cyclisation step.
