• Asymmetry induction on the [4C(4π)+3C(2π)] cycloaddition reaction of C2-functionalized furans: influence of the chiral auxiliary nature
  作者：Angel M Montaña、Pedro M Grima

  DOI：10.1016/s0040-4020(02)00452-0

  日期：2002.6

  The study of the pi-facial diastereoselectivity in the [4+3] cycloaddition reaction of thirteen different chiral 2-substituted furans with oxyallyl cations, under sonochemical and/or thermal conditions, is presented. In almost all studied furans, a cis diastereoselectivity and a high endo diastereoselectivity is observed. Decreasing the distance between the closest stereocenter of the chiral auxiliary and the reactive C2-carbon of the furan ring, increases the pi-facial diastereoselectivity, especially by using chiral furyl-sulfoxides.

  It was found that the diastereoselectivity of the Diels-Alder reaction between arynes and substituted furans is highly sensitive to substitution, which affects the reactive conformation. By varying the location of the groups on the diene partner, it is possible to obtain both excellent chemical yields and high stereoselectivity. This methodology offers rapid and convenient access to enantiomerically pure bicyclic scaffolds which are difficult to prepare by other means.

  日期：2002.3

  A study of the induction of asymmetry on the [4+3] cycloaddition reaction of some 13 C2-substituted furan derivatives with 2-oxyallyl cation is presented. The asymmetry was induced by a chiral auxiliary on C2 of furan. A vis diastereospecificity and a high endo diastereoselectivity are observed in almost all studied cases. On decreasing the distance between the stereocenter of the chiral auxiliary and the reactive C2-carbon of the furan ring, the pi-facial diastereoselectivity is increased. especially by using chiral furyl-sulfoxides.
