Abstract | In an attempt towards the total synthesis of Pseudoxylallemycin B, a homo dimeric, N-methylated macrocyclic tetrapeptidic natural product, synthesis of its epimer at position 3 (d-Tyr instead of l-Tyr) is described here. During the course of synthesis we came across a striking yet unusual observation of complete epimerization which led to the formation of 3-epi-Pseudoxylallemycin B. |
