  日期：——

  Five new 6-polyhaloacylnorkhellins were synthesized in high yields from diethoxymethyl acetate and the condensation products of khellinone with RFCO2Et and CCl3COCl. Reaction of 6-polyfluoroacylnorkhellins with primary aromatic amines yielded 6-(arylaminomethylene)-7-hydroxy-4,9-dimethoxy-7-(polyfluoroalkyl)furo[3,2-g]chroman-5-ones. © 2006 Wiley Periodicals, Inc.
