Efficient total synthesis of the cytotoxic halogenated monoterpene aplysiapyranoid D
摘要:
The first total synthesis of the antitumor marine natural product aplysiapyranoid D (1d) has been accomplished in seven steps from the dienol 2 using a key brominative cyclization that gives mainly the tetrahydropyran products rather than the expected tetrahydrofuran products.
