  Asymmetric Diels-Alder reactions with 5-menthyloxy-2-(5H)-furanone

  摘要：

  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.

  Asymmetric Diels-Alder reactions of γ-alkoxy-α-sulfinylbutenolides

  摘要：

  The synthesis of the enantiomerically pure 5-ethoxy-3-p-tolylsulfinyl-2(5H)-furanones (2a and 2b) and the study of their behaviour as dienophiles in asymmetric Diels-Alder reactions with cyclopentadiene arc reported. Depending on the reaction conditions, the pi-facial selectivity is mainly controlled by the sulfur or C-5 configurations.
