[GRAPHICS]The total synthesis of Argyrin B (1) is presented using a synthetic plan that is convergent and flexible and conserves the stereogenic centers. The unusual amino acid 4-methoxy tryptophan (6) was obtained via an enzymatic resolution. Cyclization followed by oxidative elimination of the phenylseleno cysteine to the sensitive dehydroalanine afforded synthetic 1.
