Dynamiclibraries of [n × n] imine components spontaneously simplify during a slow oxidation reaction to produce only n discrete products. The selectivity of this self-sorting process is a consequence of different oxidation rates for various imines, while the dynamic nature of the library enables self-sorting to proceed with high efficiency.
[n × n] 亚胺组分的动态库在缓慢氧化反应过程中自发地简化,仅产生 n 个离散产物。这种自分类过程的选择性是各种亚胺氧化速率不同的结果,而库的动态特性使自分类能够高效进行。

benzimidazole, quinazoline, and imidazopyridine is reported using hypervalent iodine as the key reagent. Acetoxy, aryl, iodide and nitro functional groups were introduced on the same substrate by simply shifting the reaction conditions in the presence of inorganic additives (Cs2CO3, I2, NaNO2) and the hypervalent iodine reagent (diacetoxyiodo)benzene (PIDA) underaerobicconditions. The combination
