Patent number: 10464861Abstract: Processes of forming Csp2—Csp3 bonds at the allylic carbon of a cyclic allylic compound starting material are disclosed, in which a racemic mixture of a cyclic allylic compound having a leaving group attached to the allylic carbon is reacted with a compound having a nucleophilic carbon atom in the presence of a Rh(I), Pd(II) or Cu(I) pre-catalyst and a chiral ligand. The reaction products containing the newly-formed Csp2—Csp3 bond are generated in high stereoisomeric excess, and may therefore serve as important organic building blocks in the preparation of new agrochemicals and pharmaceuticals.Type: GrantFiled: June 1, 2016Date of Patent: November 5, 2019Assignee: Oxford University Innovation LimitedInventors: Stephen P.

Patent number: 7678538Abstract: Asymmetric cyanine dyes of Formula I bind nucleic acid but not red blood cell membrane, and function as photosensitizers when rigidly bound but not when free in solution. Unbound dye thus causes minimal oxidative damage. The dyes do not substantially accumulate in red blood cells, thereby minimizing hemolysis due to oxidative damage. Biological fluids can be disinfected by mixing the fluid with these asymmetric cyanine dye that binds to nucleic acid, irradiating the mixture, and recovering clinically significant components from the biological fluid and/or assaying the fluid for pathogens.Type: GrantFiled: May 10, 2006Date of Patent: March 16, 2010Assignee: American National Red CrossInventor: Stephen J.
