The use of amine-rich N-doped carbon nanodots (NCNDs) for the photochemical radical perfluoroalkylation of organic compounds is reported. This operationally simple approach occurs under mild conditions producing valuable new C?C bonds. The chemistry is dr

The development of a proline sulphonamide-catalysed method for enantioselective and diastereoselective construction of functionalized cyclohexenones is described. Impact of catalyst structure as well as solvent effects and additives are explored. A significant substrate scope is demonstrated by variation of both the aldehyde and the enone components. Diastereoselective derivatization of the cyclohexenone scaffold illustrates its utility as a building block for chemical synthesis.
Synthesis of all-carbon, quaternary center-containing cyclohexenones through an organocatalyzed, multicomponent coupling

supporting information; experimental part, p. 3108 - 3111 (2010/09/11)
Organocatalyzed multicomponent coupling using a new ester-containing, proline aryl sulfonamide has been developed for accessing densely functionalized cyclohexenones, each containing a quaternary center in high enantio- and diastereoselectivity. In contrast to most enamine/iminium-catalyzed reactions, the use of molecular sieves was critical to optimum enantioselectivity.
Generation and intramolecular cyclization of α-sulfinyl and α-sulfonyl radicals

, p. 7805 - 7826 (2007/10/03)
α-Phenylsulfinyl and α-Phenylsulfonyl radicals are generated by the reactions of α-chlorosulfoxides and α-chlorosulfones with tributyltin hydride, respectively. High reaction concentration (0.2 M) is required to ensure efficient generations of these radic
The study of intramolecular free radical cyclizations of α-sulfonyl and α-sulfinyl radicals
Tsai,Ke,Lin
, p. 6047 - 6050 (2007/10/02)
α-Sulfonyl and α-sulfinyl radicals can be generated from the corresponding α-halosulfones and α-halosulfoxides. Our results indicate that these radicals cyclize very efficiently.
