  Chiral Amino Alcohols As Intermediates in the Stereocontrolled Synthesis of 1,3-Disubstituted Tetrahydroisoquinolines and Protoberberines

  摘要：

  An efficient stereocontrolled synthetic approach to (3S)-3-aryltetrahydroisoquinoline Sd and (1S,3S)-3-aryl-1-methyltetrahydroisoquinolines 3a-c by a Pictet-Spengler heterocyclization reaction of optically active (95% ee) (S)-1,2-diarylethylamines 2a-c is presented. An alternative route toward obtaining the epimeric derivative of 3a, tetrahydroisoquinoline (1R,3S)-6, was also achieved by a stereocontrolled ring opening process carried out on the oxazolotetrahydroisoquinoline 9. Tetrahydroisoquinoline 8 was employed for the stereoselective preparation of(5S,6S, 14S)-6-phenyl-2,3,10,11-tetramethoxyprotoberberin-5-ol (12), a new type of 5,6-disubstituted protoberberine derivative with excellent (d.e>95% by H-1 NMR) stereoselection.

• A Simple and Efficient Synthetic Route to Chiral Isopavines. Synthesis of (−)-<i>O</i>-Methylthalisopavine and (−)-Amurensinine

  日期：1997.10.1

  The isopavinan alkaloids (-)-O-methylthalisopavine (7a) and (-)-amurensinine (7d) have been synthesized in good yield and high ee from the appropriate 1,2-diarylethylamine derivatives using optically active beta-amino alcohols as chiral support. This synthetic route employs as key steps the alkylation reaction of the azomethine derivatives 2 with Grignard reagents 1 and a novel one-pot double-intramolecular cyclization of the adequately functionalized 1,2-diarylethylamines 5 to afford a series of optically active isopavines 6a-d and 7a-d.

  日期：——

  Herein, we report a concise asymmetric total synthesis of isopavine alkaloids, which feature a special azabicyclo[3.2.2]nonane tetracyclic skeleton. The key steps include iridium-catalyzed asymmetric hydrogenation of unsaturated carboxylic acids, Curtius rearrangement, and Eschweiler–Clarke methylation, which enable an enantioselective approach to isopavine alkaloids in 6–7 linear steps. Furthermore
