Gong, Lingzhen; Zhao, He; Yang, Jian; Jiang, Huanfeng; Zhang, Min published an article in 2021, the title of the article was Selective construction of fused heterocycles by an iridium-catalyzed reductive three-component annulation reaction.Computed Properties of 2567-29-5 And the article contains the following content:
Here, through an initial pretreatment of N-heteroarenes with alkyl bromide, a syn-selective construction of functional fused heterocycles, chromenoquinolinones I [R1 = H, 7-Br, 10-NO2, etc.; R2 = CH2CH=CH2, Ph, 4-MeC6H4, etc.; R3 = H, Me; R4 = Me, Ph, 2-furyl] and chromenopyranoquinolinones II [R5 = H, 10-Me, 7-Br, etc.; R6 = H, 3-MeO, 2-Br, etc.] via iridium catalyzed reductive annulation of N-heteroarenium salts with formaldehyde and cyclic 1,3-diketones or 4-hydroxycoumarins, proceeding with broad substrate scope, good functional group compatibility, readily available feedstocks, and high step and atom efficiency was described. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Computed Properties of 2567-29-5
The Article related to chromenoquinolinone preparation diastereoselective, cyclohexanedione quinolinium bromide selective reductive annulation iridium catalyzed, chromenopyranoquinolinone preparation diastereoselective, hydroxycoumarin quinolinium bromide selective reductive annulation iridium catalyzed and other aspects.Computed Properties of 2567-29-5
