Disclosed are novel compounds represented by structural Formula (XX), (XXI) or (XXII); R1, R21 and R22 are independently an aliphatic group, a substituted aliphatic group, an aromatic group or a substituted aromatic group. R2 and R12 are independently -NR4R5 or -N+C-. R3 is -H or an alcohol protecting group. R4 and R5 are independently -H or an amine protecting group. R11 is a side chain of a naturally occurring amino acid or a protected side chain of a naturally occurring amino acid. R1 and R2, and R11 and R12, taken together with the methine group to which they are bonded, can form a moiety represented by structural Formula (XXIII). R6 is -H or an amine protecting group. R7 is -H, - OH or -OR8. R8 is an alcohol protecting group. Also disclosed are methods of preparing these compounds.

La présente invention concerne de nouveaux composés représentés par la formule structurale (XX), (XXI) ou (XXII) dans lesquelles R¿1?, R¿21? et R¿22? sont indépendamment un groupe aliphatique, un groupe aliphatique substitué, un groupe aromatique ou un groupe aromatique substitué; R¿2? et R¿12? sont indépendamment -NR¿4?R¿5? ou -N?+¿?C?-¿; R¿3? est -H ou un groupe protecteur d'alcool; R¿4? et R¿5? sont indépendamment -H ou un groupe protecteur d'amine; R¿11? est une chaîne latérale d'un amino acide naturel ou une chaîne latérale protégée d'un amino acide naturel; et R¿1? et R¿2? ainsi que R¿11? et R¿12?, pris ensemble avec le groupe méthine auquel ils sont liés, peuvent former une fraction représentée par la formule structurale (XXIII); R¿6? est -H ou un groupe protecteur d'amine; R¿7? est -H, -OH ou -OR¿8?; R¿8? est un groupe protecteur d'alcool.
