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。
