- Palladium-Catalyzed Atom-Transfer Radical Cyclization at Remote Unactivated C(sp3)?H Sites: Hydrogen-Atom Transfer of Hybrid Vinyl Palladium Radical Intermediates
-
A novel mild, visible-light-induced palladium-catalyzed hydrogen atom translocation/atom-transfer radical cyclization (HAT/ATRC) cascade has been developed. This protocol involves a 1,5-HAT process of previously unknown hybrid vinyl palladium radical intermediates, thus leading to iodomethyl carbo- and heterocyclic structures.

- 1-PHENYLALKANONE 5-HT4 RECEPTOR LIGANDS
-
The present invention relates to novel 5-HT 4 receptor ligands which are 1-(5-halo-4-aminophenyl) (C 2-6)alkan-1-one derivatives in which the 5-halo-4-aminophenyl group is substituted at its 2-position with (C 1-4)alkyloxy or phenyl(C 1-4)alkyloxy and optionally substituted at its 3-position with (C 1-4)alkyloxy or substituted at its 2-and 3-positions together with methylenedioxy or ethylenedioxy and the highest numbered carbon of the (C 2-6)alkan-1-one is substituted with di(C 1-4)alkylamino, morpholin-1-yl or pyrrolidin-1-yl or optionally substituted piperidin-1-yl, piperidin-4-yl, azacyclohept-1-yl, azabicyclo[2.2.1]hept-3-yl, azabicylo[2.2.2]oct-3-yl or azabicylo[3.2. 2] non-3-yl; and the pharmaceutically acceptable salts, individual isomers and mixtures of isomers and methods of using and making such derivatives.
