摘要

在本研究中，通过ag2co3催化aza-Michael加成吡唑与乙烯基砜进行了吡唑与砜的简单杂化。n -磺基乙基化吡唑是吡唑-砜杂化物的重要组成部分，该方法具有反应条件温和、收率高、区域选择性高（N1/N2比最高可达25:1）等特点。

Pyrazole-Sulfone hybridization via silver-catalyzed regioselective aza-Michael addition of pyrazoles to vinyl sulfones: Synthesis of N-sulfonylethylated pyrazoles

In this research, the facile pyrazole-sulfone hybridization via Ag₂CO₃-catalyzed aza-Michael addition of pyrazoles to vinyl sulfones has been developed. The methodology offers an efficient and regioselective synthesis of N-sulfonylethylated pyrazoles as an important subset of pyrazole-sulfone hybrids and it featured mild reaction conditions, excellent yields and high regioselectivity (reaching the highest N¹/N² ratio of 25:1).
