efficient synthesis of β-aryl-β-mercapto ketones is achieved via a tandem aldol condensation-thia-Michael addition process using an aqueous medium and diethylamine. Addition of different thiols to α,β-unsaturated ketones, formed in situ from the condensation of acetophenone derivatives with aldehydes, led to a rapid and high yielding synthesis of the products under very mild conditions using no expensive
通过使用水性介质和二乙胺的串联羟醛缩合-硫杂-迈克尔加成工艺可以实现β-芳基-β-巯基酮的有效合成。向苯乙酮衍生物与醛的缩合反应中原位形成的α,β-不饱和酮中添加不同的硫醇,可在非常温和的条件下,无需使用昂贵的添加剂或催化剂,即可快速,高产地合成产物。通过简单过滤分离在反应混合物中自发沉淀的产物,并通过重结晶纯化。
