First fruit of a very interesting collaboration…

… with Dr. Santiago Uriel.

Thank you and congratulations!

Simple iodoalkyne-based organocatalysts for the activation of carbonyl compounds, Alegre-Requena, J. V.; Valero-Tena, A.; Sonsona, I. G.; Uriel, S.; Herrera, R. P. Org. Biomol. Chem. 2020, DOI: 10.1039/c9ob02688f

Abstract. A novel approach for the formation of bisindolylmethane derivatives (BIMs) is described as a proof of concept to evaluate the catalytic capacity of iodoalkynes. The use of these derivatives is reported as an example of simple halogen bond-based organocatalyst. This kind of activation has not been used before for the synthesis of bisindolylmethane derivatives 3. Interestingly, the preparation of 3-(1H-indol-3-yl)-1-phenylbutan-1-one (8) has been also achieved for the first time with an iodoalkyne derivative. We prove the efficiency of this family of new catalysts by developing a simple and easy operational methodology, opening the door to the development of alternative catalysts in the area of halogen bond-based organocatalysts.
