A generality-oriented and adaptive α-sulfonylation of alkynes via photoinduced multicomponent radical cross-coupling of terminal alkynes with sulfinates and a variety of alcohols, thiophenols, or selenophenols has been explored. This protocol features mild conditions, good functional group tolerability, broad substrate scope, excellent chemo-, site-, and stereoselectivity, and applicability to late-stage functionalization. It provides a modular platform for the synthesis of value-added structurally diverse α-sulfonyl-containing multisubstituted alkenes from simple precursors.

光氧化还原催化的末端炔烃的多组分 α-磺酰化


已经探索了通过光诱导末端炔烃与亚炔酸盐和多种醇、硫酚或硒酚的光诱导多组分自由基交叉偶联的炔烃的通用性和适应性α磺酰化。该方案具有条件温和、良好的官能团耐受性、广泛的底物范围、出色的化疗、位点和立体选择性，以及适用于晚期功能化的特点。它为从简单前驱体合成高附加值结构多样的含 α-磺酰基的多取代烯烃提供了一个模块化平台。
