Hypervalent iodine(III) reagents are readily available, easy to handle, and have a low toxicity and similar reactivities to those of heavy metal reagents, and hence they are used for various oxidative reactions. The oxidative cleavage of alkynes or carbonyl compounds by using bis(trifluoroacetoxy)iodo(III) pentafluorobenzene (C(6)F(5)I(OCOCF(3))(2)) has been reported. Herein, the efficient direct synthesis
高价碘(III)试剂易于获得,易于处理,并且毒性低,并且与重金属试剂的反应性相似,因此可用于各种氧化反应。据报道,使用双(三氟乙酰氧基)碘(III)五氟苯(C(6)F(5)I(OCOCF(3))(2))氧化炔或羰基化合物。在这里,通过使用C(6)F(5)I(OCOCF(3)的α-氨基酸或β-氨基醇的氧化裂解反应,可以有效地直接合成N,O-乙缩醛化合物作为Discorhabdin A的关键中间体))(2)进行说明。
