Description

Description générale

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.

Application

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

Suzuki Cross-Coupling with MIDA Boronates

• 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.
