A methodology involving a spiroborate as a chiral resolution agent has been applied to obtain unsaturated chiral-only-at-metal rhodium(III) enantiopure complexes bearing bidentate silyl-type ligands.
We discuss recent advances in the applications of cycloruthenated complexes in organic synthesis, comprising C–H activation, chiral-at-metal catalysis, Z-selective olefin metathesis, transfer hydrogenation, enantioselective cyclopropanations and cycloadditions.
Construction of chiral chroman skeletons via catalytic asymmetric [4 + 2] cyclization of ortho-hydroxyphenyl-substituted p-QMs catalyzed by a chiral-at-metal rhodium complex.
An efficient asymmetric cascade [3 + 2] annulation of N-alkoxyacrylamides with α,β-unsaturated 2-acyl imidazoles catalyzed by a chiral-at-metal rhodium complex has been developed.
An efficient asymmetric cyclopropanation of sulfoxonium ylides with α,β-unsaturated 2-acyl imidazoles catalyzed by a chiral-at-metal rhodium complex has been developed.
