  An I2-promoted, metal-free domino protocol for one-pot synthesis of 1,3,4-oxadiazoles has been developed via oxidative cleavage of C(sp2)–H or C(sp)–H bonds, followed by cyclization and deacylation. In this reaction, the use of K2CO3 as a base is found to be an essential factor in the cyclization and the C–C bond cleavage. This procedure proceeded smoothly in moderate to high yields with good functional

  通过氧化裂解C（sp 2）–H或C（sp）–H键，然后环化，已开发出I 2促进的无金属多米诺协议，用于一锅合成1,3,4-恶二唑。和脱酰作用。在该反应中，发现使用K 2 CO 3作为碱是环化和C–C键断裂的必要因素。该过程以中等至高收率顺利进行，并具有良好的官能团相容性。

  strategy for the synthesis of 1,3,4-oxadiazoles was established through direct annulation of hydrazides with methyl ketones. It was found that the use of K2CO3 as a base achieves an unexpected and highly efficient C–C bond cleavage. This reaction is proposed to go through oxidative cleavage of Csp3–H bonds, followed by cyclization and deacylation.

  1′-diphenylthiodiacetic acid dihydrazide and triethyl orthoesters in the presence of catalytic amount of glacial acetic acid resulted in the formation of three heterocyclic products: the appropriate bis(1,3,4-oxadiazol-2-yl-phenylmethyl) sulfides, 2-benzyl-1,3,4-oxadiazoles and 2-benzoyl-1,3,4-oxadiazoles. The presence of the latter two compounds is connected with carbon–sulfur fission in the molecule

  在催化量的冰醋酸存在下，对称的1,1'-二苯基硫代二乙酸二酰肼与三乙基原酸酯的反应导致形成三种杂环产物：适当的双（1,3,4-恶二唑-2-基-苯甲基）硫化物，2-苄基-1,3,4-恶二唑和2-苯甲酰基-1,3,4-恶二唑。后两种化合物的存在与起始酰肼分子中的碳硫裂变有关。通过由苯基乙酸酰肼和2-羟甲基-1,3,4-恶二唑衍生物并行合成模型1,3,4-恶二唑，证实了未预期的裂变产物的身份。

  4-oxadiazoles involves the 2-iodoxybenzoic acid/tetraethylammonium bromide mediated oxidative cyclization of hydrazide-hydrazones generated in situ from the reaction of aryl glyoxal and hydrazides. This one-pot protocol is reasonably general for the preparation of α-keto-1,3,4-oxadiazoles under mild conditions in short reaction times.

  已经开发了一种用于制备 α-keto-1,3,4-oxadiazoles 的高效和高产协议。α-酮基-1,3,4-恶二唑的形成涉及芳基乙二醛和酰肼反应原位生成的酰肼-腙的2-碘氧基苯甲酸/四乙基溴化铵介导的氧化环化。这种一锅法对于在短反应时间内在温和条件下制备 α-酮-1,3,4-恶二唑是相当通用的。
