In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Ir/Cu dual catalysis: Enantio- and diastereodivergent access to α,α-disubstituted α-amino acids bearing vicinal stereocenters, published in 2018-02-14, which mentions a compound: 415918-91-1, Name is (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, Molecular C36H30NO2P, COA of Formula: C36H30NO2P.
We describe a fully stereodivergent synthesis of a range of α,α-disubstituted α-amino acids via an Ir/Cu-catalyzed α-allylation of readily available imine esters. The introduction of a Cu-Phox complex-activated imine ester into the chiral iridium-catalyzed allylic allylation process is crucial for its high reactivity and excellent enantio- and diastereoselectivity (up to >99% ee and >20:1 dr). Importantly, the two chiral catalysts allow for full control over the configuration of the stereocenters, affording all stereoisomers of the desired products. The utility of this methodol. was demonstrated by synthesizing dipeptides and analogs of bioactive mols. in a stereodivergent manner.
As far as I know, this compound(415918-91-1)COA of Formula: C36H30NO2P can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
