A set of chiral sulfinyl imine–thioether ligands are prepared via dehydration condensation of substituted benzaldehyde and chiral sulfinamide. The activity of these ligands in Pd-catalyzed asymmetric allylicalkylation reaction is studied, and the results indicate that the structure of sulfinamide motifs has an obvious effect on the e.r. value and yield. The chiral p-tolylsulfinamide derived ligands
Horner-Emmons reaction of phosphonate amides with aldehydes leads to generation of o-substituted aryl-acrylamides. These compounds have been shown to be useful to quickly establish structure-activity relationships (SAR) for soluble guanylyl cyclase (sGC) activator drug discovery. (C) 2003 Elsevier Ltd.
