摘要
The stereochemical determination of the potent antifungal agents leupyrrin A(1) and B-1 and the total synthesis of leupyrrin A(1) are reported. The relative and absolute configuration was determined by a combination of high field NMR studies, molecular modeling, and chemical derivatization. The expedient total synthesis involves a one-pot sequential Zr-mediated oxidative diyne-cyclization/regioselective opening sequence for preparation of the unique dihydrofuran ring, a highly stereoselective one-pot approach to the butyrolactone, a challenging sp(2)-sp(3) Suzuki coupling and a high-yielding Shiina macrolactonization.
