A novel iridium/acid co-catalysed transfer hydrogenative coupling strategy, enabling direct alkylation of C(sp3)-H bond and atom-economic access to alkyl chain-lengthened N-Heteroaromatics from six-membered 2-alkyl cyclicamines and aldehydes, has been...
Deracemization of Phenyl-Substituted 2-Methyl-1,2,3,4-Tetrahydroquinolines by a Recombinant Monoamine Oxidase from <i>Pseudomonas monteilii</i>
ZMU-T01
A monoamineoxidase (MAO5) fromPseudomonasmonteilii ZMU‐T01 was first heterologously expressed in Escherichia coli BL21(DE3) and then used as a biocatalyst for the deracemization of racemic 2‐methyl‐1,2,3,4‐tetrahdroquinoline derivatives to yield the unreacted R enantiomer with up to >99 % ee. Sequence alignment revealed that MAO5 shared 14.7 % identity toward the well‐studied monoamineoxidase (MAO‐N)

Dibenziodolium salts were utilized as efficient halogen bond donor catalysts for carrying out the reduction of quinolines, one-pot reductive amination, Michael additionreaction of indoles with chalcones, and Friedel-Crafts reaction of indoles with isatin. NMR studies suggest the presence of halogen bond.
