中文摘要:
在 dimethyl 硫化物支持的 2-ethynylbenzaldehyde 和乙烯之间的分子间的 Pauson-Khand 反应能被利用综合 2-(2-formylphenyl ) cyclopentenone 高效地。这混合物和它的衍生物经历反应与 nitromethane 由亨利反应跟随了构造代替的芳香的熔化 2,3-dihydroindanones 的迈克尔增加的一个串联过程。而且,从 2-ethynylbenzaldehyde 的芳香的熔化 2,3-dihydroindanones 的直接一个壶合成被完成。
英文摘要:
The intermolecular 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 deriva- tives undergo a cascade process of Michael addition reaction followed by Henry reaction with nitromethane to con- struct substituted aromatic fused 2,3-dihydroindanones. Furthermore, direct one-pot synthesis of aromatic fused 2,3-dihydroindanones from 2-ethynylbenzaldehyde is achieved.
