  Enantioselective synthesis of each stereoisomer of the pyranoid linalool oxides: the geraniol route

  摘要：

  Each of the four enantiomerically pure tetrahydropyran linalool oxides was synthesized by an acid-catalyzed cyclization of an appropriate epoxy-alcohol obtained by consecutive Sharpless dihydroxylation (AD) and epoxidation (AE) reactions of geraniol derivatives. An interesting example of double asymmetric induction was observed during the AE of a bis(homoallylic) N-naphthylcarbammae. (C) 2000 Elsevier Science Ltd. All rights reserved.
