Memory of chirality in the transannular cyclization of cyclodecenyl radicals.
The transannular cyclization of an enantioenriched cyclodecenyl radical proceeds in a 5-exo fashion to produce scalemic bicyclo[5.3.0]decanes. This cyclization is notable because it demonstrates chirality transfer through conformational memory of an unstabilized secondary radical. [reaction: see text]
