  Enantioselective Synthesis of the Dendrobatid Alkaloid (-)-Indolizidine 207A

  摘要：

  An enantioselective synthesis of the Dendrobates alkaloid (-)-indolizidine 207A (1) is reported. The key intermediate in this synthesis is alcohol 6 (Scheme 1), prepared in four steps from geraniol with control of both relative and absolute configuration.

  Enantiogenic total syntheses of (-)-indolizidines (bicyclic gephyrotoxins) 205A, 207A, 209B, and 235B via the intramolecular Diels-Alder reaction of a chiral N-acylnitroso compound

  摘要：

  A general protocol for the enantiogenic total syntheses of a series of the 5-substituted 8-methylindolizidine class of alkaloids from the arrow poison frog, i.e., (-)-indolizidines 205A (1), 207A (2), 209B (3), and 235B (4), is described, in which a key step is the asymmetric intramolecular Diels-Alder reaction of the chiral N-acylnitroso compound 8 leading to the bicyclic oxazinolactam 7 which was utilized as a versatile common chiral intermediate for the preparation of these alkaloids. Subsequent introduction of the C-5 (in future) side chain was elaborated by means of a completely stereocontrolled process involving a Grignard reaction followed by reduction with NaBH4 in acidic media. The bicyclic oxazines 20a, 24, and 26 thus obtained were then subjected to reductive N-O bond cleavage followed by cyclodehydration using PPh3/CBr4/Et3N, which provided the (-)-enantiomers of the title alkaloids.

  indolizidine and 1,4-disubstituted quinolizidine system found in Dendrobates alkaloids has been developed. The key step for this synthesis is the highly stereoselective Michael reaction of a didehydropiperidinecarboxylate (1) to afford a trans(2,3)-cis(2,6)-trisubstituted piperidine. In this manner, the chiral formal synthesis of indolizidines 207A and 209B and the total synthesis of indolizidines

  已开发出一种通向Dendrobates生物碱中的5,8-二取代的吲哚并立核苷和1,4-二取代的喹oli嗪系的通用且灵活的途径。该合成的关键步骤是二脱氢哌啶羧酸酯（1）的高度立体选择性迈克尔反应，得到反式（2,3）-顺式（2,6）-三取代哌啶。以这种方式，已经实现了吲哚并咪唑207A和209B的手性形式合成以及喹啉并咪唑207I的吲哚并咪唑223J，235B'和Cl-顶基的总合成。
