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. WebHow many chiral Centres are present in menthol? three chiral centers The three chiral centers of menthol result in eight different stereoisomers, of which the (-)-enantiomers are depicted in Figure 1. The stereoisomers, (-)-menthol (1R, 2S, 5R), and (-)-neomenthol (1R, 2R, 5S), are naturally occurring in the essential oil of Mentha x piperita L. grass and herb
