An Efficient Method for the Preparation of Indole-,7-Azaindole-,Pyrrole-containing Tertiary Alcohols

A simple and efficient synthetic procedure for the preparation of indole-,7-azaindole-,and pyrrol-containing tertiary alcohols from indole/azaindole/pyrrole and tempo-substituted 1,3-dicarbonyl compounds were developed. the mechanistic pathway for this process involves the n-o bond cleavage of tempo-substituted 1,3-dicarbonyl compounds to form the tricarbonyl intermediate,following friedel-crafts reaction of indole/aza-indole/pyrrole with this intermediate generates the tertiary alcohol product. all the processes do not need extra catalysts,dry solvents or harsh reaction conditions.
