  Diversity Oriented Clicking (DOC) is a unified click‐approach for the modular synthesis of lead‐like structures through application of the wide family of click transformations. DOC evolved from the concept of achieving “diversity with ease” , by combining classic C−C π‐bond click chemistry with recent developments in connective SuFEx‐technologies. We showcase 2‐Substituted‐Alkynyl‐1‐Sulfonyl Fluorides

  面向多样性的点击 (DOC) 是一种统一的点击方法，用于通过应用广泛的点击转换家族来模块化合成类先导结构。DOC 从实现“轻松实现多样性”的概念演变而来，将经典的 C−C π 键点击化学与连接性 SuFEx 技术的最新发展相结合。我们展示了 2-取代的- A炔基-1-磺酰基F氟化物（SASFs）作为一类新的连接枢纽，与多种点击环加成过程相结合。通过具有一系列偶极子和环状二烯的 SASF 的选择性 DOC，我们以最少的合成步骤报告了 173 种独特功能分子的多样化点击库。SuFExable 库包含 10 个离散的杂环核心结构，这些核心结构源自 1,3- 和 1,5- 偶极子；而与环状二烯的反应会产生几种三维双环 Diels-Alder 加合物。通过对 96 孔板中的磺酰氟侧基进行 SuFEx 点击衍生化，可以通过后期修饰将文库增加到 278 种离散化合物——证明了 DOC 方法在快速合成不同功能结构方面的多功能性。

  A copper-catalyzed [2 + 2 + 1] heteroannulation of alkenes with enynyl benziodoxolones and AgNO2 involving oxidative cleavage of the C≡C bond promoted by cooperative Zn(OTf)2, KOAc, and 4 Å MS for producing 3-aryl Δ2-isoxazolines is reported. Mechanistic studies indicate that AgNO2 serves as the N/O two-atom unit source, enabling the formation of three bonds through NO2 addition across the C≡C bond

  synthesized and applied towards oxidation reactions of benzylamine derivatives. Under the optimized reaction conditions, the selectivity to oxime enhanced, leading to the main product with up to 72 %. Moreover, even α-substituted benzylamines were well tolerated and led to oximes in good isolated yields. It is important to mention; four equivalents of the harmless and inexpensive hydrogen peroxide were employed
