  Total Synthesis of Irciniastatin A (Psymberin)

  摘要：

  The total synthesis of (+)-iriciniastatin A (psymberin) is reported in 19 steps and 6% overall yield. Key reactions include a highly convergent enolsilane-oxocarbenium Ion union to generate the C8-C25 fragment and a late-stage coupling of a hemiaminal and acid chloride to complete the synthesis.
