Reductive alkylation is a practical route for a total synthesis of regioisomers of spider toxin JSTX-3, a polyamine amide which is a selective glutamate receptor antagonist and may have potential as a neuroprotective agent. The strategy is based upon a reductive alkylation step which enables one free araine to be generated regiospecifically in the new polyamine, or the regiospecific incorporation of
还原烷基化是全部合成蜘蛛毒素JSTX-3的区域异构体的实用途径,JSTX-3是一种多胺酰胺,是一种选择性的谷氨酸受体拮抗剂,可能具有作为神经保护剂的潜力。该策略基于还原性烷基化步骤,该步骤能够在新的多胺中区域特异性地产生一个游离的阿拉伯氨酸,或者在构象上限制了多胺酰胺主链的六氢嘧啶部分的区域特异性结合。
