Cytotoxic metabolites from the endophytic fungus Penicillium chermesinum: discovery of a cysteine-targeted Michael acceptor as a pharmacophore for fragment-based drug discovery, bioconjugation and click reactions
The first total synthesis and structural determination of TMC-264
摘要:
The first total synthesis and structural determination of TMC-264 has been accomplished. Regioselective bromination, regioselective methoxymethylation, and nickel(0)-Lewis acid-mediated cyclization afforded multi-functionalized 1-methyl-dibenzo[b,d]-pyran skeleton. (C) 2008 Elsevier Ltd.
