N-methylglycinate, and ethyl N-benzylglycinate have been studied under acidic, basic and neutral conditions. Such reactions have resulted in efficient and selective methodology for the synthesis of unsymmetrical 2,3,4-trisubstituted pyrrole systems.
已经研究了在酸性,碱性和中性条件下2,3-二取代的氯丙啶鎓盐和相关的合成子与甘氨酸乙酯,N-甲基甘氨酸乙酯和N-苄基甘氨酸乙酯的反应。这样的反应导致了用于合成不对称的2,3,4-三取代的吡咯体系的有效和选择性的方法。
