Three‐Step Synthesis of Arylpolyboronic Acids from Phenols via Organotin Compounds.

Abstract

Organo-boron compounds S 0040Three-Step Synthesis of Arylpolyboronic Acids from Phenols via Organotin Compounds. -Aryldi-and triboronic acids are prepared in three steps starting from readily available phenols under mild conditions. Subsequent Suzuki cross-coupling reactions afford polycyclic hydrocarbons in good yields. -(FIDELIBUS, P. M.; SILBESTRI, G. F.; LOCKHART, M. T.; MANDOLESI, S. D.; CHOPA*, A. B.; PODESTA, J. C.; Appl.
