A practical and efficient regioselective synthesis of several new chiral 4,5,6,7-tetrahydro[1,2,3]triazolo[1,5-a]pyrazines is described from α -amino acid derivatives following intramolecular 'click' reaction as the key step. The method obviates product -purification; to obtain the pure triazole products, only the solvent needs to be evaporated.
几种新的手性 4,5,6,7-四氢 [1,2,3] 三唑并 [1,5-a] 吡嗪的实用且有效的区域选择性合成描述为从分子内“点击”反应后的 α-氨基酸衍生物关键步骤。该方法避免了产品纯化;为获得纯三唑产品,只需蒸发溶剂即可。
