A highly regioselective domino metathesis reaction of 7-oxanorbornene was developed that employed an intramolecular association of an amide carbonyl group to a ruthenium metal centre. By using this reaction, twelve glutamate analogues inspired by dysiherbaine were efficiently synthesized over 12-14 steps; one of the analogues exhibited bioactivity consistent with central nervous system depression.
开发了一种7-氧杂降冰片烯的高度区域选择性多米诺复分解反应,该反应利用酰胺羰基与钌金属中心的分子内缔合。通过使用该反应,以12 - 14步高效合成了十二种受dysiherbaine启发的谷氨酸类似物;其中一种类似物表现出与中枢神经系统抑制一致的生物活性。
