title: Regioselective palladium cross-coupling of 2,4-dihalooxazoles: convergent synthesis of trisoxazoles.
abstract: A regioselective Suzuki-Miyaura cross-coupling of 2,4-dihalooxazoles followed by a Stille coupling has been successfully developed. The procedure affords convergent syntheses of trisoxazoles in high yield and in a minimum number of steps.
