  Total Synthesis of 5-N-Acetylardeemin and Amauromine:  Practical Routes to Potential MDR Reversal Agents

  摘要：

  The total synthesis of the title compounds has been accomplished. The key step involves the kinetic stereoselective conversion of 19 --> 20. The synthesis of 20 represents for the first time a direct method for constructing exo-pyrroloindoles from protected tryptophans in a highly diastereoselective manner. This step was followed by reverse prenylation (see conversion of 20 --> 27). Using the methodology worked out for the titled compounds, a practical synthesis of several promising MDR reversal agents was possible. Biological data that provided the basis for selection of candidates for advanced study are presented. Preliminary profiling of the zones of the molecules that are responsive to changes while still retaining MDR reversal ability are described. On the basis of these findings, compounds 2, 50, and 51 were selected for more extensive biological follow-up.

  The nickel catalyzed reductive coupling of allylic carbonates with chloro-cyclotryptamine analogs to construct sterically congested all C(sp3) quaternary centers has been achieved with emphasis on the substrate scope. And the using of dienyl methyleneyl carbonates coupling with a variety of tertiary alkyl halides furnished the dienylated products improved the reaction's applicability.

  easily removed via visible light irradiation under mild conditions. We found that an excited phenolate-type photocatalyst efficiently transfers an electron to the benzene ring of benzyl-derived protecting groups to generate a phenyl radical anion. The benzyl C–N or C–O bond is then mesolytically cleaved by releasing a benzyl radical. This method enables efficient deprotection of the benzyl group on amides

  苄基及其衍生物是有机合成中最常用和最广泛使用的保护基团，通常通过传统的过渡金属催化氢解或 Birch 还原来去除。氢解受到官能团相容性以及氢的易燃性和易爆性的限制，而 Birch 还原则受到易燃碱和苛刻条件的限制。在这里，我们报告在温和条件下通过可见光照射很容易去除苄基衍生的保护基团。我们发现激发的酚盐型光催化剂有效地将电子转移到苄基衍生保护基团的苯环上以产生苯基阴离子。苄基 C-N 或 C-O 键然后通过释放苄基自由基被分解裂解。该方法能够有效地脱保护酰胺、芳基胺、醚、酯和氨基甲酸酯上的苄基。具体而言，该方法在碳水化合物、肽、药物和具有多种功能的天然产物中显示出出色的化学和区域选择性。
