  Acetic acid (1R,2R,3R,4S)-2,3,4,5-tetraacetoxy-1-(6,7-dimethoxy-3,4-dihydro-isoquinolin-1-yl)-pentyl ester 在 间氯过氧苯甲酸 作用下， 以 二氯甲烷 为溶剂， 反应 0.25h， 生成 Acetic acid (1R,2R,3R,4S)-2,3,4,5-tetraacetoxy-1-(6,7-dimethoxy-2-oxy-3,4-dihydro-isoquinolin-1-yl)-pentyl ester

  名称：

  Enantioselective synthesis of (R)-(−)-laudanosine and (R)-(−)-glaucine from L-ascorbic acid

  摘要：

  L-Ascorbic acid 1 was converted into L-gulonolactone 2 by catalytic hydrogenation. Treatment of 2 with 3,4-dimethoxyphenylethyl amine 3 afforded amide 4, which in several steps was transformed into the title alkaloids in good enantiomeric excesses. Also, chromium(III) oxide is proposed as an effective catalyst for the conversion of (R)-(-)-laudanosine into (R)-(-)-glaucine. Copyright (C) 1996 Published by Elsevier Science Ltd
