Pauson‐Khand reaction between 2‐ethynylbenzaldehyde and ethylene promoted by dimethyl sulfide can be utilized to synthesize 2‐(2‐formylphenyl)cyclopentenone efficiently. This compound and its derivatives undergo a cascade process of Michael addition reaction followed by Henry reaction with nitromethane to construct substituted aromatic fused 2,3‐dihydroindanones. Furthermore, direct one‐pot synthesis of aromatic
2-乙炔基苯甲醛与二甲基硫醚促进的乙烯之间的分子间Pauson-Khand反应可用于高效合成2-(2-甲酰基苯基)环戊烯酮。该化合物及其衍生物经历迈克尔加成反应的级联过程,然后与硝基甲烷进行亨利反应,以构建取代的芳香族稠合的2,3-二氢茚满酮。此外,还可以从2-乙炔基苯甲醛直接单锅合成芳族稠合的2,3-二氢茚满酮。
