Abstract
A novel and highly efficient Pd-catalyzed approach for the synthesis of bis-heterocycles featuring both isoxazoline and methyleneindole motifs is demonstrated. The in situ formation of vinyl Pd(II) species through an alkyne-tethered carbamoyl chloride cyclization is crucial, and the innovative Pd-catalyzed carboetherification of β,γ-unsaturated oximes with vinyl Pd(II) species has been developed. This method is not only operationally straightforward but also exhibits a broad substrate scope and excellent functional group tolerance.
