An efficient Pd(II)‐catalyzed one‐pot tandem cyclization/alkylation reaction of internal alkynes has been reported. In this reaction, a wide range of structurally diverse β/;‐isoxazole aldehydes/ketones could be obtained in good to excellent yields from various alkynyl oxime ethers and allylic or homoallylic alcohols. The gram‐scale experiment and various transformations of the newly obtained products
