Abstract

A novel [3+2]-cycloaddition reaction of alkynylboronates and nitrile oxides gave the title compound, C(22)H(32)BNO(3), as a single regioisomer. The X-ray crystal structure analysis of this compound shows two independent molecules in the asymmetric unit, each with approximately coplanar isoxazole and boronate rings.
