A Mild and Simple Method for Making MIDA Boronates

submitted on 31.03.2020, 17:47 and posted on 03.04.2020, 18:11 by Aidan Kelly, Peng-Jui (Ruby) Chen, Jenna Klubnick, Daniel J. Blair, Martin D. Burke

Existing methods for making MIDA boronates require harsh conditions and complex procedures to achieve dehydration. Here we disclose that a pre-dried form of MIDA, MIDA anhydride, acts as both a source of the MIDA ligand and an in situ desiccant to enable a mild and simple MIDA boronate synthesis procedure. This method expands the range of sensitive boronic acids that can be converted into their MIDA boronate counterparts. Further utilizing unique properties of MIDA boronates, we have developed a MIDA Boronate Maker Kit which enables the direct preparation and purification of MIDA boronates from boronic acids using only heating and centrifuge equipment that is widely available in labs that do not specialize in organic synthesis.
