Safety of (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Iridium-catalyzed regio- and enantioselective allylic alkylation of fluorobis(phenylsulfonyl)methane.
Highly regio- and enantioselective allylic alkylation of fluorobis(phenylsulfonyl)methane (FBSM) has been realized by [Ir(COD)Cl]2/phosphoramidite, affording enantiopure fluorobis(phenylsulfonyl)methylated compounds bearing a terminal alkene, which could be converted to monofluoro-methylated ibuprofen in just two steps without loss of the optical purity (95% ee).
