G. Roussi et al., SYNTHESIS OF A MODEL OF CHLOROPEPTIN-I, CHLOROPEPTIN-II WESTERN SUBUNIT BY THE INTRAMOLECULAR SNAR BASED METHODOLOGY, Tetrahedron letters, 38(25), 1997, pp. 4401-4404
Formation of a biaryl ether bond between the termini of a tetrapeptide
containing a highly racemization prone amino acid by the intramolecul
ar SNAr reaction afforded two diastereomeric 16-membered macrocycles a
long with their respective atropoisomers. The (R,S,R) and its atropois
omer constituted a model of chloropeptins I, II western part. (C) 1997
