Glycosidopyrroles. Part 3. Effect of the benzocondensation on acyclic derivatives: 1-(2-hydroxyethoxy) methylindoles as potential antiviral agents.

The new of 1-(2-hydroxyethoxy)methylindole derivatives 3a-i were prepared in good yields. None of them showed any significant anti-HIV activity and therefore the benzocondensation between the 2 and 3 positions of the pyrrole ring definitely reduced the weak activity found in the analogues 1a-c.
