The structure and stereochemistry of the first bi-isoflavonoid (3S, 4S)-3,4-trans-2′,7-dihydroxy-4′-methoxy-4-[(3S)-2′,7-dihydroxy-4′-methoxyisoflavan-5′-yl]isoflavan (3) from Dalbergia nitidula are established by acid-induced condensation or photolysis of the appropriate pterocarpan and isoflavan precursors.
第一双异黄酮(3 S,4 S)-3,4-反式-2',7-二羟基-4'-甲氧基-4-[(3 S)-2',7-二羟基的结构和立体化学来自黄檀的-4'-甲氧基异黄烷-5'-基]异黄烷(3)是通过适当的翼果烷和异黄烷前体的酸诱导的缩合或光解而建立的。
