Synthesis of Acylborons by Ozonolysis of Alkenylboronates: Preparation of an Enantioenriched Amino Acid Acylboronate
A concise synthesis of acylborons was achieved by ozonolysis of alkenyl MIDA (N-methyliminodiacetic acid) boronates. This reaction exhibits excellent functional-group tolerance and is applicable to various acyl MIDA boronates and potassium acyltriflurobor
Oxidative geminal functionalization of organoboron compounds
Excellent tolerance: Stable acylboronates equipped with N-methyliminodiacetyl (MIDA) boryl groups ([B]) were prepared by using a sequence of oxidative manipulations at the boron-bound carbon center (green in scheme). Chemoselective transformations of these acylated organoboron building blocks yielded a range of multifunctionalized boron derivatives and supplied access to valuable borylated heterocycles (see scheme).
