with simpler amines through the borrowing hydrogen methodology, producing a variety of substituted secondary and tertiary benzylamines in moderate to excellent yields for the first time with an iron catalyst. Notably, we explore the versatility of this methodology in the one-pot synthesis of nonsymmetric tertiaryamines, sequential functionalization of diols with distinctly different amines, and the synthesis

phase rutile titania supported gold (Au/TiO2-R) catalyst is shown to efficientlycatalyze this CO/H2O-mediated RA undermild and convenient conditions. With this system, a broad spectrum of primary and secondary amines can be used as suitable substrates and the desired reaction can proceed favorably in a highly chemoselective, efficient and atom-economical fashion. In particular, this protocol can also
Cholinergic Agents Structurally Related to Furtrethonium. 2. Synthesis and Antimuscarinic Activity of a Series of N-[5-[(1'-Substituted-acetoxy)methyl]-2-furfuryl]dialkylamines
In the first part of this study, devoted to the discovery of selective antimuscarinic agents, (+/-)- N-[5-[(1'-phenyl-1'-cyclohexylacetoxy)methyl]-2-furfuryl]dimeth yla mine (5a) proved to be at least 20 times more potent in the rat ileum and bladder than in guinea pig atria. Several (+/-)-N- [5-[(1'-substituted-acetoxy)methyl]-2-furfuryl]dialkylamine analogs of 5a were subsequently prepared. This
