2-(Halomethyl)-4,5-diphenyloxazoles are effective, reactive scaffolds which can be utilized for synthetic elaboration at the 2-position. Through substitution reactions, the chloromethyl analogue is used to prepare a number of 2-alkylamino-, 2-alkylthio- and 2-alkoxy-(methyl) oxazoles. The 2-bromomethyl analogue offers a more reactive alternative to the chloromethyl compounds and is useful in the C-alkylation
2-(卤甲基)-4,5-二苯基恶唑是有效的反应性支架,可用于2-位的合成修饰。通过取代反应,氯甲基类似物用于制备许多2-烷基氨基-,2-烷硫基和2-烷氧基-(甲基)恶唑。2-溴甲基类似物为氯甲基化合物提供了更具反应性的替代物,可用于稳定的(丙二酸酯)碳负离子的C-烷基化,如氧杂丙嗪的简明合成所举例说明的那样。
