The combination of N-fluorobenzenesulfonimide (NFSI) with diselenides allowed the rapid decarboxylative tri- or tetrafunctionalization of alkynyl carboxylic acids under catalyst-free room-temperature conditions. This reaction offers an novel and facile route to polyseleno-substituted enamines.
straightforward method for the synthesis of a new class of small organic fluorophores bearing both [2.2]paracyclophane and naphthalene subunits using an intramolecular dehydrogenative Diels–Alder reaction as a key step. These compounds are characterized by a compact three-dimensional structure as well as through-spaceconjugated push–pull systems, and possess interesting spectroscopic characteristics that may be

Ruthenium-catalyzedasymmetric [2 + 2] cycloadditionsbetweenchiralacyl camphorsultam-functionalized alkynes and bicyclicalkenes were examined, providing adducts with complete exo stereoselectivity in good overall yield and enantioselectivity (up to 99% and 166:1, respectively), as well as appreciable diastereoselectivity (up to 163:1). The diastereoselectivity showed dependence on the solvent and
