  Studies on Difficult Intramolecular Hydroaminations in the Context of Four Syntheses of Alkaloid Natural Products

  摘要：

  Examples of intramolecular alkene hydroaminations forming six-membered ring systems are rare, especially for systems in which the double bond is disubstituted. Such cyclizations have important synthetic relevance. Herein we report a systematic study of these cyclizations using recently developed Cope-type hydroamination methodologies. Difficult intramolecular alkene hydroaminations were used as key steps in syntheses of 2-epi-pumiliotoxin C, coniine, N-norreticuline and desbromoarborescidine A. This effort required the development of optimized hydroamination conditions to improve the efficiency of the cyclizations. Collectively, our results show that Cope-type cyclizations can be achieved on a variety of challenging substrates and proceed under similar conditions for both N-H and N-substituted hydroxylamines.

  Total synthesis and evaluation of lamellarin α 20-Sulfate analogues

  摘要：

  In order to explore the influence of sulfate groups on the bioactivity profiles of marine alkaloids of the lamellarin class, three such alkaloids, lamellarin alpha, lamellarin alpha 13,20-disulfate and lamellarin H, were synthesized and their activities against HIV-1 integrase and cancer cell lines were compared with those of lamellarin alpha 20-sulfate, which is a selective inhibitor of HIV-1 integrase. Lamellarin alpha does not inhibit HIV-1 integrase but shows moderate cytotoxicity with good cell line selectivity. Lamellarin alpha 13,20-disulfate is a moderate inhibitor of both HIV-1 integrase and cancer cell lines. Lamellarin H is a more potent inhibitor of HIV-1 integrase but lacked the specificity required to be medicinally useful. (C) 2002 Elsevier Science Ltd. All rights reserved.

  DOI：10.1071/ch99022

  日期：——

  The benzofuran (4), a ring-fused analogue of the potent antimitotic agent combretastatin A4 (1), has been prepared by a convergent route involving 5-endo-dig iodocyclization of o-hydroxytolan (5) as the key step. Compound (4), which has been characterized crystallographically as well as spectroscopically, is inactive as a tubulin-binding agent.
