Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, ACS Catalysis called Enantioselective Synthesis of Polycyclic Indole Derivatives Based on aza-Morita-Baylis-Hillman Reaction, Author is Gao, Yuning; Xu, Qin; Shi, Min, which mentions a compound: 21778-81-4, SMILESS is O=CC(N1)=CC2=C1C=CC(OC)=C2, Molecular C10H9NO2, Category: pyridazine.
A chiral phosphine-catalyzed asym. aza-Morita-Baylis-Hillman reaction between indole-derived sulfonyl imines and bis(3-chlorophenyl)methyl acrylate has been developed, giving the desired adducts in good yields and enantiomeric excess values along with the further transformations to polycyclic indoles such as dihydropyrido[1,2-a]indole and dihydropyrazino[1,2-a]indole skeleton.
After consulting a lot of data, we found that this compound(21778-81-4)Category: pyridazine can be used in many types of reactions. And in most cases, this compound has more advantages.
