The chromone siphulin (382) was synthesized by reaction of 2-hydroxy-4-benzyloxy-6-n-heptylacetophe-none with 2-carboxy-3,5-dibenzyloxyhomophthalate in the presence of NaH to give tri-O-benzylprotosiphulin this yielded siphulin after acid-induced dehydration and hydrogenolysis 461) (see Scheme 129). [Pg.150]
