Synthesis of a model of chloropeptins I, II western subunit by the intramolecular SNAr based methodology
摘要:
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 a model of chloropeptins I, II western part. (C) 1997 Published by Elsevier Science Ltd.
