A convergent formal [4 + 2] cycloaddition reaction for the construction of structurally appealing spiro-tetrahydroquinolines has been developed, in which, a one-pot reaction is established for the in situ generation of two reagents, a cyclic alkyne and an
Gallium(III)-promoted halocyclizations of 1,6-diynes
Strom, Kyle R.,Impastato, Anna C.,Moy, Kenneth J.,Landreth, Adrian J.,Snyder, John K.

Cyclization of 1,6-diynes promoted by stoichiometric Ga(III) halides produces vinyl halides in good to excellent yields. Under acidic conditions, initially formed iodocyclization products undergo in situ Friedel-Crafts cyclizations, giving access to iodoi
Catalytic enantioselective synthesis of chiral tetraphenylenes: Consecutive inter- and intramolecular cycloadditions of two triynes

Triynes having a phenylene-bridged 1,5-diyne moiety were transformed into substituted tetraphenylenes by the title sequence. A cationic Rh-ligand species catalyzed this highly enantioselective reaction. This protocol is a new and easy approach to the cons

A rhodium complex of N-heterocyclic carbene (NHC) has been developed for intra- and intermolecular [4 + 2] and intramolecular [5 + 2] cycloaddition reactions. This is the first use of a transition-metal NHC complex in a Diels-Alder-type reaction. For the
