Herein we report a protocol for the direct visible-light-mediated alkenylation of alkyl boronic acids at room temperature without an external Lewis base as an activator, and we propose a mechanism involving benzenesulfinate activation of the alkyl boronic acids. The protocol permits the efficient functionalization of a broad range of cyclic and acyclic primary and secondary alkyl boronic acids with
本文中,我们报告了一种在室温下直接可见光介导的烷基硼酸烯基化的方案,而无需使用外部路易斯碱作为活化剂,并且我们提出了一种涉及烷基烷基硼酸的苯磺酸盐活化的机理。该协议允许使用各种烯基砜有效地官能化各种环状和无环伯和仲烷基硼酸。我们通过制备或功能化多种药物和天然产品证明了其实用性。
