    Two new highly stereoselective routes to (2R,3S,4R)-3-(tert-butyldimethylsilanyloxy)-2,4-dimethyl-5-oxopentanoic acid methoxymethylamide, an important intermediate in natural product synthesis, are described. Both schemes are considerably shorter and less expensive than methods previously reported. The title compound was then converted to direct precursors of C1–C7 and C17–24 fragments of the potent

    日期:2006.3
    A highly stereoselective synthesis of the C(29)–C(39) fragment of the potent immunosuppressant sanglifehrin A has been accomplished by a sequence involving 16 steps (18% overall yield) from N-propionyloxazolidinone 9. Key steps are a diastereoselective hydroboration, and a diastereoselective epoxidation of an allylic alcohol followed by a 1,5-anti boron-mediated aldol reaction of methyl ketone 4 with

    reaction. Careful comparison of the spectroscopic data for the synthetic C3–C48 degradation fragment to that reported by the isolation group revealed a structural misassignment in the lactol region of the naturally derived degradation product. Ultimately, the data reported for the naturally derived aflastatin A C3–C48 degradation lactol (6a, R = H) were attributed to its derivative lactol trideuteriomethyl
