The Suzuki reaction applied to the synthesis of novel pyrrolyl and thiophenyl indazoles

Molecules. 2012 Apr 16;17(4):4508-21. doi: 10.3390/molecules17044508.

Abstract

The paper describes the Suzuki cross-coupling of a variety of N and C-3 substituted 5-bromoindazoles with N-Boc-2-pyrrole and 2-thiopheneboronic acids. The reactions, performed in the presence of K(2)CO(3), dimethoxyethane and Pd(dppf)Cl(2) as catalyst, gave the corresponding adducts in good yields. The methodology allows the facile production of indazole-based heteroaryl compounds, a unique architectural motif that is ubiquitous in biologically active molecules.
