Indole rings are widespread among drugs, natural and bioactive compounds. For this reason, indoles having diverse substitution patterns represent targets of great interest for organic chemists. The 3,5,7-substitution pattern is not frequently encountered in the literature, but it represents a very interesting option for the development of novel bioactive compounds. Professor Jonathan Sperry (University of Auckland, New Zealand) has recently described a new strategy for accessing 3,5,7-substituted indoles.

Professor Sperry said: “In a cyclization-free approach to heteroaromatic construction, indoles harboring a rare substitution pattern are attainable using an iridium-catalyzed triborylation–protodeborylation sequence.”
