First convergent synthesis of (+)-myxothiazol A(1) was achieved based on modified (one-pot) Julia Olefination between (3,5R)-dimethoxy-(4R)-methyl 6-oxo-(2E)-hexenamide (2), corresponding to left-side of the final molecule, and E-4-2'-(1S,6-dimethylheptadiene)-(2,4'-bis-thiazole)-4-methybenzothiazole sulfone (4) corresponding to right-side.
