    Synthesis of Antifungal Glucan Synthase Inhibitors from Enfumafungin
    摘要:
    An efficient, new, and scalable semisynthesis of glucan synthase inhibitors 1 and 2 from the fermentation product enfumafungin 3 is described. The highlights of the synthesis include a high-yielding ether bond-forming reaction between a bulky sulfamidate 17 and alcohol 4 and a remarkably chemoselective, improved palladium(II)-mediated Corey-Yu allylic oxidation at the highly congested C-12 position of the enfumafungin core. Multi-hundred gram quantities of the target drug candidates 1 and 2 were prepared, in 12 linear steps with 25% isolated yield and 13 linear steps with 22% isolated yield, respectively.

    A Concise Synthesis of (S)-N-Ethoxycarbonyl-α-methylvaline
    摘要:
    [GRAPHICS]A practical and efficient protocol for the three-step synthesis of (S)-N-ethoxycarbonyl-alpha-.methylvaline 3 is described which utilizes readily available commercial starting materials. The key transformations involve resolution-crystallization of tartrate salt 6 followed by a one-pot procedure for the preparation of 3 which is isolated as the dicyclohexylamine salt in 45% overall yield and in 91-95% ee.
