Synthetic Route of C10H9NO2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Catalytic Asymmetric [3 + 2] Annulation via Indolyl Copper-Allenylidene Intermediates: Diastereo- and Enantioselective Assembly of Pyrrolo[1,2-a]indoles. Author is Zhang, Jian; Ni, Tao; Yang, Wu-Lin; Deng, Wei-Ping.
A catalytic asym. decarboxylative [3 + 2] annulation via indolyl copper-allenylidene amphiphilic intermediates has been developed. This protocol offers a straightforward method for the synthesis of biol. important pyrrolo[1,2-a]indoles bearing contiguous quaternary and tertiary stereogenic centers with excellent diastereo- and enantioselectivities (up to >20:1 dr and >99% ee). In addition, the diversity-oriented synthesis of pyrrolo[1,2-a]indoles was achieved via versatile transformations of the alkyne-containing cycloadducts.
