标题 :Pyrogallol synthesis of anti-atherogenic furochromones
发明人：GAMMILL RONALD B
权利人:UPJOHN CO
摘要:The present invention provides a total synthesis of known intermediates useful in the synthesis of khellin and antiatherosclerotic analogs thereof from pyrogallol. Pyrogallol is converted to 3,6,7-benzofurantriol triacetate using zinc chloride and chloracetanitrile, then catalytically reduced and deactoxylated at the 3 position to yield the corresponding 2,3-dihydrofuran. This substance is subjected to a Fries rearrangement to the corresponding diol, the phenolic hydroxyl group of which is then selectively alkylated. This yields 6-hydroxy-7-alkoxy-5-benzofuranyl methyl ketone, a known intermediate for the production of 4-desmethoxy khellin and analogs thereof. This compound is then selectively alkoxylated at the 4 position using lead tetraacetate or thallium (III) nitrate in an alkanol solvent to yield known chemical intermediates in the preparation of khellin and analogs thereof.
