amines in the presence of Me3Al. The reaction proceeds via a domino nucleophilic addition with subsequent intramolecular cyclisation. This method provides a wide variety of substituted 1-aminoisoquinolines with good functional group tolerance. Furthermore, the synthetic utility of this protocol was demonstrated in the successful synthesis of the antitumor agent CWJ-a-5 in gram scale.
通过在 Me 3 Al存在下用胺处理 2-(2-oxo-2-
苯乙基)
苄腈,实现了一种用于构建
1-氨基异喹啉的简单有效的方案。该反应通过多米诺亲核加成和随后的分子内环化进行。该方法提供了多种具有良好官能团耐受性的取代
1-氨基异喹啉。此外,该协议的合成效用在克级抗肿瘤剂 CWJ-a-5 的成功合成中得到了证明。
