trans-2-(Trifluoromethyl)cyclopropylboronic acid N-methyliminodiacetic acid (MIDA) ester 5 was synthesized as a pure diastereomer from vinylboronic acid MIDA ester and (trifluoromethyl)diazomethane in a single step. An X-ray study confirmed the trans-stereochemistry around the cyclopropyl ring. Use of 5 in Suzuki reactions, with a variety of aryl or heteroaryl coupling partners, provided trans-2-(
This disclosure concerns a protected cyclopropylboronic acid comprising a substituted cyclopropyl group and a boronic ester group having a protecting group. The protecting group is an N-methyliminodiacetic acid (MIDA) group or MIDA-based group.
