asymmetric Strecker reaction/alkylation method. Of the four types of substrates tested for intramolecular acylation, those with a 4-alkoxyl group do not react, those with a 4-bromo substituent give lower conversions, while those without a 4-substituent or with a 4-methyl group work well to give the desired cyclization products. Based on these investigations, a new route for preparing (S)-1-aminoindan-1
通过立体中心策略的自动再生或使用不对称的Strecker反应/烷基化方法合成α,α-二取代的氨基酸衍生物。在进行分子内酰化测试的四种底物中,具有4-烷氧基的底物不发生反应,具有4-溴取代基的底物的转化率较低,而没有4-取代基或具有4-甲基的底物的反应良好。得到所需的环化产物。基于这些研究,开发了一种制备(S)-1-氨基茚满-1,5-二羧酸(S)-AIDA及其类似物的新途径。
