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.

Xiong, Ying published the artcileEnantioselective Total Synthesis of (-)-Hamigeran F and Its Rearrangement Product, Application In Synthesis of 725251-81-0, the publication is Organic Letters (2022), 24(28), 5161-5165, database is CAplus and MEDLINE.

Herein, we report the first enantioselective total synthesis of the highly complex hamigeran diterpenoid (-)-hamigeran F and its rearrangement product. The synthetic strategy features key steps of asym. hydrogenation, Horner-Wadsworth-Emmons olefination, and intramol. Friedel-Crafts acylation to construct the [6,6,5]-tricyclic skeleton bearing three consecutive stereocenters, a sequence of steps involving Rosenmund reduction, Wittig reaction, dihydroxylation to assemble the α-acetoxy ketone group, and an intramol. aldol reaction to build the tetracyclic core structure.
