Description General description 4-Tolyl-α-MIDA-boryl aldehyde is a-boryl aldehyde derivative. It can be synthesized from oxiranyl MIDA boronates, via rearrangement. Application This boronic acid derivative is in a series of the first known stable α-boryl aldehyde species. Through the employment of the MIDA-protected boronic ester, this building block has been shown as a precursor to the synthesis of unnatural amino acids.
