摘要：

Lithium perchlorate suspended in dichloromethane is an efficient catalyst (4 - 25 mol%) for stereoselective Diels-Alder, hetero-Diels-Alder and regioselective 1,3-Claisen rearrangements; this process is milder, safer and environmentally less precarious than the use of 1 - 5 molar solutions of LiClO4 in ether described previously in the literature.
