N2′ reaction of vinyl oxazine with Grignard reagents: A flame dried two-necked flask was charged with cuprous cyanide (8.5 mg, 0.1 mmol) and dry ether (10 mL) under nitrogen atmosphere. The reaction flask was cooled to 0 °C in ice-salt mixture and a solution of Grignard reagent in ether (1 M, 0.5 mL, 0.5 mmol) was added dropwise. After stirring for 10 min, a solution of vinyl oxazine (79 mg, 0.2 mmol) in ether was added dropwise through cannula for 10 min. The reaction mixture was stirred for an additional hour, and then brought to room temperature and stirred for another 1 h. After the complete disappearance of the starting material on TLC, the brownish reaction mixture was quenched with saturated ammonium chloride, extracted with ethyl ether (3 × 20 mL), washed with water, and dried over anhydrous sodium sulfate. The solvents were removed in vacuo and the residue was purified by flash column chromatography on silica gel (ethyl acetate-hexane, 3:1) to afford the respective protected N-acetylsphingosines 7a-e.
