enantioconvergent or a kinetic resolution step was used in the reaction of tertiary cyclobutenols with arylboroxines under a Ni/modified SPINOL catalytic system. This reaction allows the direct use of free hydroxyl groups as leaving groups while the strained ring remains untouched and provides enantioenriched cyclobutenes having a tertiary hydroxyl or an all-carbon quaternary stereocenter.
