Question & Answer
  • Electrophilic substitution of an indole as opposed to benzofuran and benzothiophene Regioselectivity in electrophilic aromatic substitution of benzofuran and indole This response as to the regioselectivity of the electrophilic aromatic substitution of indole left me with a few more questions than it did answers. In figure 3b, does the pi bond in the bottom half of the benzene on t...more+ Jul 01 2021
  • N,N-Dimethyl-2-(indol-3-yl)glyoxylamide from indole I would like to know how to obtain the following molecule, whose technical name should be something like N,N-dimethylindol-3-ylglyoxylamide (let's call it DMIG for short) One of the constraints being that I'd like to limit myself to compounds that are relatively easy/cheap (and, of course, legal) t...more+ Jun 30 2021
  • Which atoms in indole possess the greatest amount of electron density? Presumably the amine acts as an electron donor, but that would suggest extra electron density of the adjacent carbons, making them more shield, which isn't seen in the results in the image below. Specifically I'm wondering what causes the carbon with a chemical shift of 111 ppm to be less deshielde...more+ Jun 29 2021
  • Fischer indole synthesis: significance of choice of acid catalyst Lately, as a matter of interest, I have been studying sigmatropic rearrangements. I came across the Fischer indole synthesis, whose Wikipedia article states: The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an...more+ Jun 24 2021
