• Vinylboronic acid MIDA ester is an air and chromatographically stable boronic acid surrogate for Suzuki-Miyaura cross-coupling. It can also be used in Heck and oxidative Heck reactions as well as in olefin metathesis to provide the cross-coupled product.
• It is compatible with a wide range of common synthetic reagents that allows functionalization to synthesize structurally complex boronic acid surrogates.
• It undergoes cyclopropanation and epoxidation to yield corresponding MIDA cyclopropane and oxirane, respectively.
• It can be used as one of the major reagents for the scalable synthesis of potent cytotoxin, Leiodermatolide and for the total synthesis of (−)-Blepharocalyxin D.

MIDA boronates as stable boronic acid surrogates for classically challenging cross-couplings

Suzuki Cross-Coupling with MIDA Boronates

General description

Vinylboronic acid MIDA ester, like other MIDA boronates, possesses the capacity for controlled, in situ slow-release of boronic acids under aqueous basic conditions allowing the cross-coupling of classically challenging substrates.

Preparation of trans-(2-bromovinyl) MIDA Boronate and Vinyl MIDA Boronate from the Corresponding Silanes

Due to the instability of some boronic acids, the Burke group has developed very practical syntheses of some of the more challenging MIDA boronates. For instance, while trans-(2-bromovinyl) MIDA boro...
