2-substituted 4-oxo-4-arylbutanal derivatives from commercially available or easily accessible alkynes and vinylsulfoxide substrates has been developed. Extension of the methodology to the use of 1-cycloalkenyl sulfoxides allowed the facile synthesis of five-, six-, and seven-membered-ring cycloalkyl-1-one backbone. Subsequently, the tetrahydrocycloalkyl[b]pyrrole derivatives, which are found in many active
已经开发了一种有效且直接的金催化方案,用于从市售或易于获得的炔烃和乙烯基亚砜底物合成2-取代的4-氧代-4-芳基丁醛衍生物。方法的扩展到使用1-环烯基亚砜使得可以容易地合成五,六和七元环的环烷基-1-一主链。随后,以良好的产率分离出了在许多活性药物成分中发现的四氢环烷基[ b ]吡咯衍生物。机理研究突出了在此过程中a中间体的[3,3]-σ重排。
