  Total synthesis of tovophyllin B

  摘要：

  The first total synthesis of tovophyllin B (2), an antimicrobial xanthone derived from mangosteen. has been accomplished through a convergent strategy from building blocks 6 and 7 involving lithium-mediated coupling, dehydrative cyclization, and 6 pi electrocyclization as key steps.
