Rb is methyl, ethyl, n-propyl, iso-propyl, n-butyl, tert-butyl, cyclohexyl or phenyl; or Ra and Rb are linked together to form a five or a six-heterocyclic membered ring with the sulfoxide group;
R3 is adamantyl, 2,4,6-trimethylphenyl, 2,6-di-iso-propylphenyl, 2-methyl-6-tert-butylphenyl, 2-iso-propyl-6-methylphenyl, 2-iso-propyl-phenyl, 2,6-di-ethylphenyl, 2-ethyl-6-methylphenyl, 2,4,6-trifluorophenyl, 2,6-difluorophenyl, 3,5-di-tert-butylphenyl, 2,4-dimethylphenyl or 2-methyl-phenyl;
R4 is 2,4,6-trimethylphenyl, 2,6-di-iso-propylphenyl, 2-methyl-6-tert-butylphenyl, 2-iso-propyl-6-methylphenyl, 2-iso-propyl-phenyl, 2,6-di-ethylphenyl, 2-ethyl-6-methylphenyl, 2,4,6-trifluorophenyl, 2,6-difluorophenyl, 3, 5-di-tert-butylphenyl, 2,4-dimethylphenyl or 2-methyl-phenyl;
R1 is hydrogen and R2 is unsubstituted phenyl, substituted phenyl, C1-C6 alkyl or substituted 1-propenyl; or R1 and R2 are linked together to form an optionally substituted indenylidene;
R11 is hydrogen or methyl, R12 is hydrogen or methyl, R13 is hydrogen and R14 is hydrogen;
RX is methyl, hydrogen or Cl; Ry is hydrogen; Rw is hydrogen; Rz is Cl, t-butyl, hydrogen or phenyl; or Rx and Ry are linked together to form an unsubstituted bicyclic or polycyclic aryl or a substituted bicyclic or polycyclic aryl; or Rw and Rz are linked together to form an unsubstituted bicyclic or polycyclic aryl or a substituted bicyclic or polycyclic aryl; or Ry and Rw are linked together to form an unsubstituted bicyclic or polycyclic aryl or a substituted bicyclic or polycyclic aryl.
