An efficient gold and chiral phosphoric acid cooperatively catalyzed enantioselective oxidative cyclization/Mannich-type addition reaction of homopropargyl amides with nitrones was developed, which provided chiral pyrrolidin-3-ones I [R = Me, Et, iPr, etc.; Ar1 = Ph, 4-ClC6H4, 2-furanyl, etc.; Ar2 = Ph, 4-ClC6H4, 4-BrC6H4, etc.] in high yields with excellent enantioselectivities under mild conditions. This reaction employed stable and readily available alkynes as non-diazo carbene precursors, which provided a 100% atom economy method with high bond formation efficiency.

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 Organocatalytic Double Ugi Reaction with Statistical Amplification of Product Enantiopurity: A Linker Cleavage Approach To Access Highly Enantiopure Ugi Products, published in 2020-01-17, which mentions a compound: 2129645-31-2, Name is (11bS)-4-Hydroxy-2,6-bis(4-nitrophenyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, Molecular C32H27N2O8P, Application In Synthesis of (11bS)-4-Hydroxy-2,6-bis(4-nitrophenyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide.

Here we report an organocatalytic double Ugi reaction combining the enantioselective process and ee enhancement in a single operation to afford the chiral Ugi products with very high ee values. Both bisisocyanides and bisanilines tethered by carbonate and diester, resp., were designed to accomplish this double multicomponent reaction that formed 10 new chem. bonds (4 C-N, 2 C-C, 2 C-O, and 2 N-H bonds). The strategy was further applied for the fast construction of an enantiomerically enriched macrocycle.

There is still a lot of research devoted to this compound(SMILES：O=N(=O)C1=CC=C(C=C1)C=2C=C3C(=C4C2OP(=O)(O)OC5=C(C=C6C(=C54)CCCC6)C7=CC=C(C=C7)N(=O)=O)CCCC3)Application In Synthesis of (11bS)-4-Hydroxy-2,6-bis(4-nitrophenyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, and with the development of science, more effects of this compound(2129645-31-2) can be discovered.
