Conformation-directed macrocyclization reactions

A review. The importance of conformational pre-organization in successful macrocyclization reactions was recognized ever since Eschenmoser's synthesis of vitamin B12 and Woodward's synthesis of erythromycin. Different approaches to productive preorganizati ...

A novel strategy towards the total synthesis of cyclopeptide alkaloids

Jieping Zhu

Cyclic peptides I (R = benzyl, allyl; R1 = NO2, NH2, H), which contain the macrocyclic aryl ether skeleton of some naturally occurring alkaloids such as pandamine, were prepd. Key to the synthetic strategy was the cyclocondensation of the linear peptides I ...

A Convergent Synthesis of 14-Membered F-O-G Ring Analogs of the Teicoplanin Binding Pocket via Intramolecular SNAr Reaction

Jieping Zhu

An intramol. SNAr reaction for efficient macrocyclization via biaryl ether formation was developed for syntheses of the 14-membered macrocycles I and II (R = NH2, NO2) related to F-O-G ring of teicoplanin. Chloride as well as fluoride could be used as the ...
