  Total Synthesis of (+)-Mycalamide A

  摘要：

  A convergent total synthesis of (+)-mycalamide A is described. A Yb(OTf)(3)-TMSCI catalytic system is used to synthesize a trioxadecalin ring system, which contains the right segment of mycalamide A. In addition, a tetrallydropyran ring, which is the left segment, is constructed with use of a novel one-pot delta-lactonization protocol. Both segments are prepared from a common starting material, D-mannitol. These segments are then coupled and the functional groups are transformed to synthesize (+)-mycalamide A.

  The details of a convergent total synthesis of (+)-mycalamide A are described. Yb(OTf)3−TMSCl-catalyzed cross-aldol reaction conditions are used to synthesize the right segment of mycalamide A. In this reaction, an acid-sensitive aldehyde reacts with methyl trimethylsilyl dimethylketene acetal without epimerization to provide the desired aldol adduct. Additionally, a tetrahydropyran ring, which is

  Theopederin D, a cytotoxic metabolite from a sponge of the genus Theonella, was synthesised in 14 steps (11.1% overall yield) from two advanced intermediates previously used in a synthesis of mycalamide B. A formal synthesis of pederin from similar intermediates is also reported.

  A general modular approach to the members of the pederin family of antitumour agents is exemplified by syntheses of mycalamide B and theopederin D as well as a formal synthesis of pederin. All three compounds are prepared from 6-lithio-2,3-dimethyl-4-phenylselenomethyl-3,4-dihydro-2H-pyran and 2-(3-chloropropyl)-3,3-dimethyl-3,4-dihydro-2H-pyran-4-one.
