    摘要: The present invention provides a new strategies for the synthesis of compounds of the rocaglamide family and related natural products. The synthetic approach generally involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by an enantioselective 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile in the presence of a TADDOL derivative. This approach can be used for the formation of adducts containing an aglain core structure. Methods of the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-κB-dependent conditions.
