Typical Procedure for the Synthesis of 3 and 4 General procedure: An oven-dried 25 mL Schlenk tube was charged with N-aryl hydroxamic acid 2 (1.5 eq., 0.3 mmol), Cu(OTf)2 (20 mol %, 0.04 mmol) and 4Å MS (50 mg), and the tube was evacuated and purged with argon for three times. Anhydrous DCE (1 mL) was added, and then a DCE solution (1 mL) of ynamide 1 (1.0 eq., 0.2 mmol) was added dropwise via syringe over 30 min. After stirring at 45 °C for 2 h, the reaction mixture was filtered through a short Celite pad. The filtrate was concentrated and purified by flash column chromatography on silica gel using ethyl acetate/petroleum ether (v/v, 1:4 to 1:2) as eluent to afford the desired products 3 or 4.
