Synthesis and Structure–Activity Relationship Study of Biliatresone, a Plant Isoflavonoid That Causes Biliary Atresia
摘要:
We report the first synthesis of the plant isoflavonoid biliatresone. The convergent synthesis has been applied to the synthesis of several analogs, which have facilitated the first structure-activity relationship study for this environmental toxin that, on ingestion, recapitulates the phenotype of biliary atresia.

Several new compounds were obtained as degradationproducts from a new substance from yeast during the elucidation of its structure as 2-(6-hydroxy-2-methoxy-3,4-methylenedioxyphenyl)-benzofuran. The structures of these new degradationproducts were proved by synthesis and are: 1,5-dimethoxy-2,3-methylenedioxybenzene ( V I I ) , 5-ethoxy-1-niethoxy2,3-methylenedioxybenzene ( IX), l-ethoxy-5-methoxy-2
