  The First Total Synthesis of (+)-Bullatacin, a Potent Antitumor Annonaceous Acetogenin, and (+)-(15,24)-bis-epi-Bullatacin

  摘要：

  This paper reports the first total synthesis of the natural product (+)-bullatacin (1), a representative of potent antitumor Annonaceous acetogenins, as well as a stereoisomer (+)-(15,24)-bisepi-bullatacin (2). In this synthesis, a new, efficient method has been developed to introduce the gamma-lactone into the bistetrahydrofuran skeleton through in situ alkylation of epoxide 4 by the alpha-sulfonyl carbanion of phenyl sulfone 5. The methylated gamma-lactone was successfully synthesized by a sequence of reactions comprising an aldol reaction, an acidic lactonization, and elimination under mild, basic condition.
