Abstract: Consecutive intermolecular/intramolecular cyclization between N-arylglycine derivatives and 2-hydroxylstyrenes was realized through radical cation salt-initiated sp3 C–H bond oxidation. This reaction provided a new route to forge this biologically important polycyclic benzofuroquinoline skeleton in a single… read more here.

Abstract: A crucial step in the formation of mono-aminoboranes (R2N-BH2) from the corresponding imine-BH3 adducts, under mild reaction conditions, is the 1,3-hydride shift. We offer experimental and theoretical insights into this... read more here.
