Moreover, menthol inhibited TPA-induced skin hyperplasia and … WebModification of the R-groups leads to highly efficient catalysts. C 1-chiral ligands can also be very selective as has been shown by Togni who developed a range of ligands, here exemplified by Josiphos. The ligand contains “two” chiral centers, one at the carbon atom and the other involves facial chirality of the cyclopentadienyl plane.
