RT Journal Article T1 Cyclization by Catalytic Ruthenium Carbene Insertion into Csp3-H Bonds A1 Cambeiro Cambeiro, Fermín A1 López Estévez, Susana A1 Varela Carrete, Jesús Ángel A1 Saá Rodríguez, Carlos K1 Alkynyl derivatives K1 Carbenes K1 Cyclization K1 Ruthenium K1 Spiro compounds AB A novel tandem Ru-catalyzed carbene addition to terminal alkynes/insertion of Csp3–H bonds in alkynyl acetals, ethers and amines has been accomplished under mild conditions. This cascade provides an efficient approach to form complex spiro and fused bicyclic structures in 1,5- and 1,6-hydride shift/cyclization sequences from vinylcarbene Ru intermediates.
