•Simple approach to N-sulfinyl α-aminophosphine sulfides and phosphines.•Access to chiral ligands from readily available starting materials.•A number of potential uses.•Transition metal ligands.•Nucleolophilic catalysts.•Amino acid surrogates.The diastereoselective synthesis of N-sulfinyl α-aminophosphine sulfides and phosphines is reported. These molecules are synthesized by formation of sulfinyl imine followed by diastereoselective addition of a diphenylphosphine sulfide. The product N-sulfinyl α-aminophosphine sulfides can be converted to phosphines through removal of the sulfur by reaction with Raney nickel. Hydrolysis of the sulfinyl group provides an amine that can then be attached to other ligands or structural scaffolds.Download high-res image (73KB)Download full-size image

A rhodium–BozPHOS based complex is reported. This complex is competent in catalyzing the [4+2+2] cycloisomerization of cyclooctatrienes in moderate to good yields. The X-ray crystal structure of this complex is reported, along with formation of both bicyclic and tricyclic cyclooctatrienes.
