Herein we report a new approach to the synthesis of 2,4-bifunctionalised cyclopentenones via one-pot conversion of 2-furaldehyde with morpholine followed by concomitant 1,4 addition and elimination. This protocol has also been extended to afford 2-hydroxy, 2-amino and 2-phenyl cyclopentenones.

氨基和2-苯基
环戊烯酮。
