Using commercially available natural amino acids (L-Val, L-Leu, L-Phe) as chiral precursors, a series of N-substituted imidazole derivatives containing chiral groups was synthesized from the condensation reaction of amino acids, formaldehyde, glyoxal, and ammonia. Through esterification, reduction, chlorination, and subsequent substitution by thiols, chiral thioethers containing imidazole rings were
以市售天然氨基酸(L-Val、L-Leu、L-Phe)为手性前体,通过氨基酸、甲醛、乙二醛、氨的缩合反应合成了一系列含有手性基团的N-取代咪唑衍生物. 通过酯化、还原、氯化以及随后的硫醇取代,合成了含有咪唑环的手性硫醚,并优化了合成条件。所有中间体和最终产物均通过 NMR、ESI MS、HR MS 和 IR 进行表征。
