Observation of unusual outer-sphere mechanism using simple alkenes as nucleophiles in allylation chemistry

open access: yesNature Communications
Transition-metal catalyzed allylic substitution reactions of alkenes are among the most efficient methods for synthesizing diene compounds, driven by the inherent preference for an inner-sphere mechanism.

Highly efficient construction of angular polycycles

open access: yesNature Communications
Angular tricyclic and polycyclic skeletons feature typical cores in an intriguing type of natural products. We herein report the Lewis acids-catalyzed dearomative (3 + 2) cycloadditions of donor-acceptor cyclopropanes with benzene ring, by which ...
