Development of practical methodologies for the synthesis of functionalized benzoboroxoles
摘要:
2-Formylphenylboronic acids upon reaction with activated olefins such as acrylates, methyl vinyl ketone, and acrylonitrile provide functionalized benzoboroxoles. The corresponding homologated benzoboroxoles were synthesized via the reaction of 2-formylphenylboronic acids with alpha-bromomethylacrylates. (C) 2010 Elsevier Ltd. All rights reserved.
