(+)-FusarisetinA belongs to a group of acyl tetramic acid natural products that show potential anticancer activity. Equisetin, a biogenetically related acyl tetramic acid, contains the basic skeleton of (+)-fusarisetinA. We proposed that equisetin and (+)-fusarisetinA share a biosynthetic pathway that starts with naturally occurring (S)-serine and an unsaturated fatty acid. In support of this hypothesis, we have demonstrated that a cyclization sequence involving an intramolecular Diels-Alder reaction followed by a Dieckmann cyclization of polyenoylamino acid yielded equisetin. The aerobic oxidation of equisetin, promoted by either MnIII/O2 or a reactive oxygen species (ROS) produced by visible-light chemistry, gave peroxyfusarisetin, which could be easily reduced to (+)-fusarisetinA. We report herein detailed information on the biogenetic synthesis of equisetin and (+)-fusarisetinA. Make the change to bio! Biomimetic synthesis of equisetin and (+)-fusarisetinA was achieved based on a biosynthetic hypothesis. An intramolecular Diels-Alder reaction followed by a Dieckmann cyclization of polyenoylamino ester furnished equisetin. The aerobic oxidation of equisetin to give (+)-fusarisetinA was mediated by a MnIII/O2 system or reactive oxygen species (ROS) (see scheme). Copyright

Herein we report the full details of our efforts toward the application of Pauson-Khand reaction for the stereoselective construction of the trans-decalin subunit with a C16 quaternary stereocenter of fusarisetin A, which led to the asymmetric total synth
Total synthesis of (-)-fusarisetin A and reassignment of the absolute configuration of its natural counterpart

The first total synthesis of (-)-fusarisetin A, the enantiomer of naturally occurring acinar morphogenesis inhibitor (+)-fusarisetin A, was accomplished in 13 steps, leading to the reassignment of the absolute configuration of the natural product. The synthesis featured a Lewis acid-promoted intramolecular Diels-Alder reaction, a Pd-catalyzed O→C allylic rearrangement, a chemoselective Wacker oxidation, and a Dieckmann condensation/hemiketalization cascade.
