发现了由K 2 S 2 O 8和可见光光氧化还原催化介导的可见光照射串联氧化芳基迁移/羰基形成反应。所提出的转化提供了以伴随羰基形成的1,4-芳基转移的区域选择性方式从容易获得的均炔醇衍生物直接获得重要的α-丙二烯醛/酮衍生物。操作简单和底物范围广泛表明该方法在合成高功能α-丙二烯醛/酮衍生物方面具有巨大潜力。
A novel copper‐catalyzed one‐pot functionalization of homopropargylic alcohols that involves trifluoromethylation, aryl migration, and formation of a carbonyl moiety has been developed. This reaction constitutes the first direct conversion of homopropargylic alcohols into CF3‐containing 3‐butenal or 3‐buten‐1‐one derivatives in a regioselective manner. Mechanistic studies indicate that the 1,4‐aryl

A tandem sulfenylation/cyclization method to build the scaffold of methylthiofurans with homopropargylicalcohols and DMTSM has been developed. The DMTSM is employed as methylthiolation agent for the CS bond formation in this transformation. Various substituted homopropargylicalcohols proceed successfully and the corresponding 3-methylthiofurans are afforded in ideal yields under mild conditions.
