Acylation of activated aromatic substrates under mild conditions with (RCO)2O/Me2S/BF3
Kiselyov, Alexander S.

An efficient procedure for acylation and perfluoroacylation of activated aromatic substrates under mild conditions using the system (RCO)2O/Me2S/BF3 in CH2Cl2 is described. It is believed that dimethylacylsulfonium salts, RCOSMe2+RCO2BF3-, are the active acylating agents.

A cobalt-catalyzed annulation of the C(sp2)-H/N-H bond of indoloamides with alkynes assisted by 8-aminoquinoline is reported for the synthesis of six-membered indololactams. The use of salicylaldehyde as the ligand is crucial for this transformation. The protocol has a broad scope for both alkynes and indoles. Preparing an active Co complex illustrates that salicylaldehyde plays a key role in the C-H activation step. The synthetic applications are proven by the gram-scale reaction and one-step construction of the multicyclic 5-HT3 receptor antagonist.

Efficient Synthesis and Biological Activity of Novel Indole Derivatives as VEGFR-2 Tyrosine Kinase Inhibitors
Zhang,Xu,Wang,Kang
, p. 3006 - 3016 (2018/02/21)
A series of novel indole derivatives were synthesized as potent inhibitors for the vascular endothelial growth factor receptor 2 (VEGFR-2) tyrosine kinase. Among those, compound 10b demonstrated the highest growth inhibition rate of 66.7% against the VEGFR-2 tyrosine kinase at 10 μM which indicates that indole-benzothiazole might be the favorable structure. The binding mode of compound 10b with VEGFR-2 tyrosine kinase was evaluated by molecular docking.
