资源简介：
The synthesis of fluorinated azabicycles
from tert-butyldimethylsilyl-protected N-containing cyclic
enynols using inexpensive BF3·OEt2 is described.
In this reaction, BF3 reacts as both the Lewis acid and
the fluoride source for cyclization/fluorination of the TBS-protected
cyclic N-containing enynols. The method provides
an easy access to fluorinated azabicycles where a new C(sp2)–F bond and a new bicyclic skeleton are generated at ambient
temperature within 1–13 min under metal-free reaction conditions.
