An efficient synthesis of tetrahydrocarboline-type products and polycyclic spiroindolines has been achieved. The transformation proceeds via rhodium(II)-catalyzed intramolecular annulations of indolyl- and pyrrolyl-tethered N-sulfonyl-1,2,3-triazoles. The reaction could be tuned toward either the formal [3 + 2] cycloaddition or the C–H functionalization reaction depending on the electronic and structural

Methods for treating and/or preventing disease conditions caused or induced or aggravated by microbes, especially bacteria, by inhibiting DNA methyltransferase activity, such as by administering to an animal a DNA methyltransferase inhibitor, are disclosed, along with methods of reducing or ablating virulence in bacteria by inhibiting DNA methyltransferase activity.
through a cascadereaction between 2‐isocyanoethylindole and alkylidene malonates catalyzed by a chiral N,N′‐dioxide/MgII catalyst. Fused polycyclic indolines containing three stereocenters were afforded in good yields with excellent diastereo‐ and enantioselectivities through a Michael/Friedel–Crafts/Mannich cascade. When 2‐substituted 2‐isocyanoethylindoles were used, spiroindoline derivatives were obtained
