Participants

Reaction Steps

To a solution of ethyl (3S)-morpholine-3-carboxylate (3.80 g) in a mixture of tetrahydrofuran (40 ml) and water (40 ml) was added a solution of allyl chloroformate (3.36 ml), in tetrahydrofuran (3 ml) under ice-cooling with stirring, keeping the pH between 8.5 and 9.5 with 4N aqueous sodium hydroxide. After stirring for 30 minutes, the mixture was extracted with ethyl acetate (100 ml), dried over magnesium sulfate, and evaporated to give ethyl (3S)-4-allyloxycarbonylmorpholine-3-carboxylate (5.83 g) as a syrup.
