Catalysis by lithium perchlorate in dichloromethane: Diels-Alder reactions and 1,3-Claisen rearrangements
Reetz,Gansauer
, p. 6025 - 6030 (2007/10/02)
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 tha
Chelation-Controlled Facially Selective Cyclocondensation Reactions of Chiral Alkoxy Aldehydes: Syntheses of a Mouse Androgen and of a Carbon-Linked Disaccharide

, p. 1256 - 1268 (2007/10/02)
Magnesium bromide in tetrahydrofuran catalyzes the cycloaddition of a variety of chiral alkoxy aldehydes with activated butadienes.The stereochemistry of these products is such that they can be rationalized as arising from a reacting conformer in which th
