Synthesis and antitumor-evaluation of cyclopropyl-containing combretastatin analogs
摘要:
Several derivatives of combretastatin have been prepared bearing a cyclopropyl unit instead of the natural occurring cis-double bond. Final products and synthetic intermediates were evaluated for their cytotoxic properties in two human cancer cell lines. (C) 2009 Elsevier Ltd. All rights reserved.

by their difficult synthesis. A modular approach from olefin materials is enabled by the discovery of the electron donor–acceptor (EDA) interaction between 2-substituted benzothiazolines and N-hydroxyphthalimide esters. These complexes are activated by visible light without photocatalysts, and the benzothiazoline reagent plays a triple role as a photoreductant, a stereoselective hydrogen-atom donor
