Several β-substituted alanines are synthesised in high yields by a Michael addition of nucleophiles to N-acyl-N-(tert-butoxycarbonyl)dehydroalanine methyl ester, using mild reaction conditions and simple work-up procedures. The same method can be applied to dipeptides containing dehydroalanine.
通过使用温和的反应条件和简便的后处理步骤,将亲核试剂通过迈克尔加成反应加成到N-酰基-N-(叔丁氧羰基)脱氢丙
氨酸甲酯上,可以高效合成几种β-取代的丙
氨酸。同样的方法也适用于含有脱氢丙
氨酸的二肽的合成。
