Reaction of 3,4-ethylenedioxyphenyldiazonium chloride with ethyl 2-methylacetoacetate and subsequent cyclization of the 3,4-ethylenedioxyphenylhydrazone of ethyl pyruvate gives a 1:4 mixture of 4,5- and 5,6-ethylenedioxy-2-etoxycarbonylindoles, respectively, from which 4,5- and 5,6-ethylenedioxyindoles are formed by subsequent hydrolysis and decarboxylation.Mannich and Vilsmeyer reactions as well as acetylation and azo coupling have been studied for 5,6-ethylenedioxyindole.
