The first formal intramolecular 1,3-insertion into O[sbnd]Si bond of rhodium(II) azavinyl carbene have been developed, and valuable phthalan derivatives could be synthesized efficiently. In addition, various functional groups could be introduced to the pr
Cycloisomerization of aromatic homo and bis-homopropargylic alcohols via catalytic ru vinylidenes: Formation of benzofurans and isochromenes

Ru-catalyzed cycloisomerizations of aromatic homo- and bis-homopropargylic alcohols effectively afford benzofurans and isochromenes. These processes proved to be chemo- and regioselective (5-, and 6-endo cyclizations) derived from key Ru vinylidene intermediates. The presence of an amine/ammonium base-acid pair is crucial for the catalytic cycle.
Cobalt-Mediated Cycloadditions En Route to Natural Products: A Novel Total Synthesis of Steroids via the One-Step Construction of the B,C,D Framework from an A-Ring Precursor

The first application of the cobalt-mediated intramolecular cyclization of α,δ,ω-diynenes to annulated cyclohexadienes in natural product synthesis is described by demonstrating its feasibility in a versatile and efficient steroid synthesis, including a n
