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 Copper-catalyzed highly enantioselective synthesis of cyclic allylic and homoallylic alcohols with dialkylzinc reagents, published in 2005-02-01, 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, Product Details of 415918-91-1.
The copper-phosphoramidite catalyzed addition of dialkylzinc reagents to racemic or meso allylic epoxides can be synthetically exploited in different ways, depending on the substrates and reaction conditions used.
The article 《Copper-catalyzed highly enantioselective synthesis of cyclic allylic and homoallylic alcohols with dialkylzinc reagents》 also mentions many details about this compound(415918-91-1)Product Details of 415918-91-1, you can pay attention to it, because details determine success or failure
