  Asymmetric synthesis of 2-exo-aminonorbornane-2-endo-carboxylic acid derivatives

  摘要：

  The Diels-Alder reaction of cyclopentadiene with N-acetyl-alpha,beta-didehydroalaninate of (-)-cis-3-hydroxy isobornyl neopentyl ether yields the corresponding 2-endo(exo)-acetamido-5-norbornene-2-exo(endo)-carboxylates with total diastereofacial selectivity and with a preference for the cycloadduct with the ester group placed at the endo position. So this dienophile is complementary with the previously described (-)-menthyl N-acetyl-alpha,beta-didehydroalaninate for the asymmetric synthesis of 2-aminonorbornane-2-carboxylic acids, since with the latter dienophile exo cycloadducts are preferably obtained with a high diastereofacial selectivity.
