A new class of chiral dienophiles, 5-alkoxy-2(5H)-furanones, has been developed. Both enantiomers of 5-menthyloxy-2(5H)-furanone are readily available in enantiomerically pure form, starting from furfural and d- or l-menthol. Excellent diastereoselectivities (d.e. greater-than-or-equal-to 99%) are obtained in thermal Diels-Alder reactions with several cyclic and acyclic dienes. The use of silyl dienol ethers has resulted in new routes to enantiomerically pure cyclohexanones in a highly regioselective manner.

A short and efficient synthesis of both enantiomerically pure 2,3-(Cyclohexylidenedioxy)-4-cyclopentenones 4 and ent-4 from the readily avaiable 5-menthyloxy-2[5H]-furanones 1 and ent-1 is presented. The key step is the substrate control led diastereoselective dihydroxylation of 1 and ent-1. Copyright (C) 1996 Elsevier Science Ltd
