In present study, four salicylic acid derivatives viz., 2-acetoxybenzoic acid (2a), 2-(1H-indol-2-yl)benzoic acid (3a), 5-chloro-2-acetoxybenzoic acid (2b) and 5-chloro-2-(1H-indol-2-yl)benzoic acid (3b) were synthesized and studied for molecular docking on 3JUS and 3UPI protein selected from pdb. The studies show that all of the four synthesized compounds were found to be docked. Compound 3a and 3b showed the best ligand pose energy -10.8163 kcal/mol and -11.1354 kcal/mol with docking run: elapsed time 9 s and 12 s, respectively in respect of 3JUS Further, compounds 3a and 3b showed the best ligand pose energy -9.17851 and -9.54722 kcal/mol with docking run: elapsed time 10 and 14 s, respectively in case of 3UPI. Hence, studies showed that 5-chloro-2-(1H-indol-2-yl)benzoic acid (3b) emerged as potent compound which might show diverse nature of biological and therapeutic activity.

A new entry to the total synthesis of isocryptolepine (cryptosanguinolentine), isolated from Cryptolepis sanguinolenta, was achieved by constructing a tetracyclic ring system through a microwave-assisted tandem Curtius rearrangement and electrocyclic reac
Isoindolo[2,1-a]indol-6-one-a new pyrolytic synthesis and some unexpected chemical properties
Crawford, Lynne A.,Clemence, Nathan C.,McNab, Hamish,Tyas, Richard G.
experimental part, p. 2334 - 2339 (2009/02/02)
Isoindolo[2,1-a]indol-6-one 1 is formed by a sigmatropic shift-elimination-cyclisation cascade by flash vacuum pyrolysis (FVP) of methyl 2-(indol-1-yl)benzoate 7 at 950 °C. The dihydro compound 16 is easily obtained by catalytic reduction of 1, but the reaction is very sensitive to steric effects at the 11-position. Attempted ring-opening of 1 in basic methanol provides an equilibrium of isoindolo[2,1-a]indol-6-one 1 and the ester 19. Lithium aluminium hydride reduction of 1 provides the alcohol 22 which can be dehydrated to a mixture of 23 and 24 by FVP at 800-950 °C.

The synthesis of 22 2-aryl-1H-indoles, including 12 new compounds, has been achieved via Pd- or Rh-mediated methodologies, or selective electrophilic substitution. All three methods were based on elaborations from simple indole precursors. SAR studies on
