Radical cascades using enantioenriched 7-azabenzonorbornenes and their applications in synthesis
Beilstein Journal of Organic Chemistry, 2008 Tandem deoxygenation–neophyl-type radical rearrangement–electrophile trapping using xanthates from 7-azabenzonorbornadienes gives 3-exo-substituted 2-aza-5,6-benzonorbornenes, which in some cases undergo isomerisation to (aminomethyl)indenes.

Skeletal contraction: A novel strategy to access multisubstituted cyclobutane
Green Synthesis and Catalysis, 2022 The polysubstituted and spirocyclic cyclobutanes were efficiently constructed by the utilization of a novel skeletal contraction strategy which only took one-step synthesis from the readily accessible pyrrolidines.
