We herein describe the development of a dimerization procedure for amino acids to prepare 2,5‐disubstituted thiazoles and oxazoles in the presence of Na2S⋅9H2O and H2O, respectively. These approaches enabled the direct formation of five‐membered ring systems bearing two different heteroatoms from two amino acid units. Mechanically, decarboxylation, deamination, S/O insertion, cyclization and gradient
本文中,我们描述一个二聚化过程的发展,为
氨基酸以制备
钠的存在下2,5-二取代的
噻唑和
恶唑2 S⋅9H 2氧,氢2,分别O操作。这些方法能够直接形成带有两个
氨基酸单元中两个不同杂原子的五元环系统。在机械上,脱羧,脱
氨基,S / O插入,环化和梯度氧化过程涉及低聚物的形成。
