资源简介：
Several dozen spirocyclic
sesquiterpenoids known as the bromo-chamigrenes
have been isolated to date. Yet, despite their unique structures,
synthetic efforts toward this collection have been modest. Herein,
we outline two strategies to generate their skeletons based on (1)
a biomimetic bromonium-induced polyene cyclization using BDSB (Et2SBr·SbCl5Br) and (2) a Diels–Alder
reaction which ultimately delivered four members of the class. In
addition, X-ray crystallography reveals that one member has a structure
in need of revision.
