of 2-acetylnaphthalene with benzaldehydes under microwave irradiation affords chalcones which undergo facile and clean cyclizations with hydrazines RNHNH2 (R= H, Ph, Ac) to afford 3,5-arylated 2-pyrazolines in quantitative yields, also under microwave irradiation and in the presence of dry AcOH as cyclizing agent. The results obtained indicate that, unlike classical heating, microwave irradiation results
2-乙酰萘与苯甲醛在微波辐射下的缩合得到查尔酮,其与肼 RNHNH2(R=H、Ph、Ac)进行轻松和清洁的环化,以定量产率提供 3,5-芳基化 2-吡唑啉,同样在微波辐射下和在存在干燥的 AcOH 作为环化剂。获得的结果表明,与传统加热不同,微波辐射导致更高的产率、更短的反应时间(2-12 分钟)和更清洁的反应。
