A microwave-irradiated solvent-free pinacol rearrangement of hydrobenzoin substrates catalyzed by a combination of N-fluorobenzenesulfonimide and FeCl3·6H2O was developed. Its selectivity was first investigated by density functional theory (DFT) calculations. Then the functional group tolerance was examined by synthesizing a series of substrates designed based on the insight provided by the DFT calculations
研究了N-氟苯磺酰亚胺和FeCl 3 ·6H 2 O的催化作用,对微波加热的氢安息香素底物进行了无溶剂的频哪醇重排反应。首先通过密度泛函理论(DFT)计算研究了其选择性。然后,通过合成一系列基于DFT计算提供的见解而设计的底物,来检查官能团的耐受性。该方法的应用通过有效的一锅合成(±)-latifine和(±)-cherylline进行了证明,它们都是从芳基马鞭草科植物中分离出来的4-芳基四氢异喹啉生物碱。
