Wang, Lin-Xuan; Qiu, Bin; An, Xiao-De; Dong, Pei-Zhen; Liu, Rui-Bin; Xiao, Jian published an article about the compound: 5-Methoxy-1H-indole-2-carbaldehyde( cas:21778-81-4,SMILESS:O=CC(N1)=CC2=C1C=CC(OC)=C2 ).Formula: C10H9NO2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:21778-81-4) through the article.
An unprecedented organocatalytic cascade aldimine condensation/[1,6]-hydride transfer/Mannich-type cyclization of indole-2-carbaldehydes with o-aminoanilines was developed to assemble polycyclic indole-2,3-fused diazocanes in one step. This novel methodol. featured high step- and atom-economy, was redox-neutral and metal-free, and occurred at room temperature It opened a new window for the application of hydride transfer chem. in constructing medium-sized ring structures.
