Amidyls in radical cascades. The total synthesis of (±)-aspidospermidine and (±)-13-deoxyserratine
摘要:
Concise routes to aspidospermidine and 13-deoxyserratine are described, hinging on a cascade starting from an amidyl radical and allowing the construction of the key indolizidine cores in one step. (C) 2008 Elsevier Ltd. All rights reserved.

Compounds of the formula (I) which are modulators of chemokine receptor activity useful in the prevention or treatment of certain inflammatory and immunoregulatory disorders and diseases, allergic diseases, atopic conditions including allergic rhinitis, dermatitis, conjunctivitis, and asthma, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis, and pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which chemokine receptors are involved.
A cascade radical cyclization starting from an amidyl radical has been used for the construction of (+/-)-aspidospermidine. This approach has also been developed for the preparation of a tricycle whose framework is contained in the stemona alkaloids.
