SEGPHOS is a chiral ligand developed by Takasago that is used in asymmetric synthesis It was developed after BINAP and was investigated since it has a narrower dihedral angle between the aromatic faces This was predicted and then confirmed to increase the enantioselectivity and activity of metal complexes of SEGPHOS.

The system employs Cu‐DTBM‐SEGPHOS as the catalyst, diethoxymethylsilane as the stoichiometric reductant, and O‐benzoylhydroxylamines as the electrophilic nitrogen source This hydroamination reaction is compatible with differentially substituted vinylsilanes, thus providing access to amino acid mimics and other valuable chiral organosilicon compounds. Product page for reference 3BR0159, with CAS and name RuCl(pcymene)((S)dtbmsegphos®)Cl. In the presence of DTBM‐SegPhos as a chiral ligand the products are formed with up to 95 % ee Our protocol appears to be particularly suited for the enantioselective desymmetrization 32 of prochiral β‐oxy‐substituted cyclobutanols that fail to react in a similar fashion under Rh catalysis.
