  Application of Peptidyl Radicals into a New Radical Cascade Leading to Unsaturated γ-Lactams

  摘要：

  Radical cyclization of dipeptides 1a-h proceeds smoothly to give five- and seven-membered rings in good to moderate total yields using Stork's catalytic tin hydride method. A radical is generated on a protecting group and translocated to the peptide moiety. Following a cyclization reaction, the vinyl radical can abstract hydrogen from a benzyl group on an amine, which results in elimination of the protected amine group. Encouraging results have notably been obtained with amino acids other than glycine.

  condensed dihydropyridones 6 could be synthesized from a-amino esters 2 or 3 and o-bromobenzyl bromides or heterocyclic analogues 1. These products resemble isoquinoline and β-carboline alkaloid structures and could be stereoselectively transformed into condensed 4-hydroxytetrahydropyridines 7 and 8 by reaction with Grignard reagents or reduction. Treatment of condensed 4-allyl or 4-homoallyl-4-hydroxypyridines

  光学活性缩合二氢吡啶酮 6 可以由α-氨基酯 2 或 3 和邻溴苄基溴或杂环类似物 1 合成。这些产物类似于异喹啉和 β-咔啉生物碱结构，可以通过以下方式立体选择性转化为缩合 4-羟基四氢吡啶 7 和 8与格氏试剂反应或还原。用 N-碘代琥珀酰亚胺处理缩合的 4-烯丙基或 4-高烯丙基-4-羟基吡啶 8 会发生卤环化成桥接的三环四氢吡啶 9 和 10。
