  Synthesis of Amaryllidaceae alkaloids, siculine, oxocrinine, epicrinine, and buflavine

  摘要：

  Three crinane type of alkaloids isolated from Amaryllidaceae family were synthesized by taking advantage of the PIFA-mediated intramolecular p-p' diphenol coupling reaction of norbelladine derivatives. Furthermore, buflavine was also prepared by using the p-p' diphenol coupling followed by dienone-phenol rearrangement as a key step. (C) 2004 Elsevier Ltd. All rights reserved.

  Highly pharmaceutically relevant Amaryllidaceae alkaloids have been accessed by a versatile electro-organic key transformation, including a precursor of the acetylcholinesterase inhibitor galantamine, used as FDA-approved drug for the treatment of Alzheimer's disease. Spirodienone-type intermediates were obtained in a regioselective and sustainable anodic key transformation from nature-derived starting
