  • Synthesis of (5R, 7S, 13S)-13-methoxy-1,6,8-trioxadispiro[4.1.5.3]pentadecane
    作者:Rosa L. Dorta、Angeles Martín、Ernesto Suárez、Thierry Prangé

    日期:1996.7
    The synthesis of (5R, 7S, 13S)- and (5S, 7S, 13S)-13-methoxy-1,6,8-trioxadispiro[4.1.5.3] pentadecane from tri-O-acetyl-d-glucal, by a convenient homologation of C-1 and C-6 atoms which led to an appropriate dihydroxyl intermediate 7, is reported. The key steps for the construction of the two spiroacetal systems involved a double, step by step, radical abstraction promoted by (diacetoxyiodo)benzene

  • Syntheses of Chiral Dispiroacetals from Carbohydrates
    作者:Rosa L. Dorta、Angeles Martín、José A. Salazar、Ernesto Suárez、Thierry Prangé
    DOI:10.1021/jo972023a
    日期:1998.4.1
    The syntheses of trioxadispiroacetals from carbohydrates are described. (5R,7S,13R)-13-Methoxy-1,6,8-trioxadispiro[4.1.5.3]pentadecane (23) and (5S,7S,13R)-13-methoxy-1,6,8-trioxadispiro[4.1.5.3]pentadecane (24) were prepared starting from D-galactose. The construction of the lateral tetrahydrofuran and tetrahydropyran rings was realized by homologation at C-1 and C-6 by appropriate tethers possessing a terminal primary alcohol. The cyclization of these alcohols at C-1 and C-5, respectively, was performed with (diacetoxyiodo)benzene and iodine in order to generate the alkoxy radicals which undergo an intramolecular hydrogen abstraction reaction. The diastereoisomers (5R,7S,13S)-13-methoxy-1,6,8-trioxadispiro[4.1.5.3]pentadecane (37) and (5S,7S,13S)-13-methoxy-1,6,8-trioxadispiro[4.1.5.3]pentadecane (38) were prepared starting from tri-O-acetyl-D-glucal using a suitable methodology in which homologation and intramolecular hydrogen abstraction were again the key steps. We believe that this protocol could be easily extended to other tricyclic dispiroacetal ring systems.
