Zhao, Jing published the artcileSynthesis of Benzoxaboroles by ortho-Oxalkylation of Arylboronic Acids with Aldehydes/Ketones in the Presence of Bronsted Acids, Recommanded Product: (3-Methoxy-5-methylphenyl)boronic acid, the publication is Organic Letters (2021), 23(6), 1986-1990, database is CAplus and MEDLINE.
Herein the authors describe a simple and efficient synthesis of benzoxaboroles from arylboronic acids and aldehydes or ketones in the presence of a Bronsted acid. This method greatly simplifies the starting materials and reduces the number of reaction steps. The reaction can also be accomplished with acetals and ketals. The reaction has a wide substrate scope and high practicability.
