Preparation and biological evaluation of key fragments and open analogs of scleritodermin A
摘要:
The synthesis of key fragments of scleritodermin A. their assembly, and their biological evaluation as cytotoxic and anthelmintic were performed. Highlights of the synthetic route include formation of the alpha-ketoamide linkage and use of stereocontrolled reactions. Open analogs of this natural product were obtained using a convergent strategy. (C) 2010 Elsevier Ltd. All rights reserved.

The first totalsynthesis of the originally proposed and revisedstructure of scleritodermin A, along with an isomer, were achieved by the use of an alpha-azido carboxyl group serving as the key alpha-ketoamide precursor, thus leading to a revision of the structure originally proposed for natural scleritodermin A.
