Abstract

Abstract The paper describes a rapid and efficient synthesis for the isolation of protected indazolylboronic esters. These compounds were synthesized by reaction between prepared protected haloindazoles and bis (pinacolato) diboron. The effects of solvent, temperature, reaction time, and the nature of halogen atom as well as protecting group were investigated. Additionaly, these compounds reacted either with aryl halides in a Suzuki-Miyaura cross- ...
