  描述：

  N,N-diisopropyl-8-(tert-butyldimethylsilyloxy)-2-hydroxy-1-naphthamide 在 4-二甲氨基吡啶 、 四丁基氟化铵 作用下， 以 四氢呋喃 、 二氯甲烷 为溶剂， 生成 (+)-(aS,1'S,4'R)-N,N-diisopropyl-8-methoxy-2-{4',7',7'-trimethyl-3'-oxo-2'-oxabicyclo[2.2.1]heptanecarbonyloxy}-1-naphthamide

  名称：

  Synthesis of atropisomeric 2,8-dioxygenated N,N-diisopropyl-1-naphthamides via kinetic resolution under Sharpless asymmetric dihydroxylation conditions

  摘要：

  A kinetic resolution approach under Sharpless asymmetric dihydroxylation conditions was used to synthesize enantio-enriched atropisomeric N,N-diisopropyl-1-naphthamides possessing oxygenated functionalities at both the C2 and C8 positions. A significant influence of the substrate structures on the efficiency of the kinetic resolution was observed. (+)-(aS)-N,N-Diisopropyl-2[2'-(E)-butenoyloxy]-8-methoxy-1-naphthamide is obtained in 35% yield with 94.3% ee after treating the racemate with 3.5 mol% each of Os and (DHQD)(2)-PHAL at 0degreesC for 22 h.
