was developed. Under undivided electrolytic cell conditions, a variety of sulfonylated N-heterocycles and O-heterocycles, such as tetrahydrofurans, tetrahydropyrans, oxepanes, tetrahydropyrroles, piperidines, δ-valerolactones, etc., were efficiently prepared from easily accessible unsaturated alcohols, carboxylic acids, and N-tosyl amines without the need for additional metal or exogenous oxidant.
开发了一种实用且有效的电化学分子内氨基磺酰化或氧磺酰化内部烯烃,该烯烃配备有侧氮或以氧为中心的亲核试剂与亚磺酸钠。在不分开的电解槽条件下,以易得的不饱和醇、羧酸、和否-tosyl 胺,无需额外的金属或外源氧化剂。稳健的电化学转化具有出色的氧化还原经济性、高非对映选择性和广泛的底物特异性,这为含砜杂环化合物提供了一种通用和实用的途径,并将促进基于这种电合成的相关合成和生物学研究。
