Reduction of a series of substituted flavanones afforded synthetic access to flavan-4-ols and was followed for some of them by an SN2-type acid-catalysis in methanol to provide 4-methoxyflavans. The stereochemistry of these compounds was established by 1H and 13C NMR data. Flavan-4-ols and 4-methoxyflavans have been resolved into enantiomers which are being evaluated as anticancer drugs.
一系列得到合成获得黄烷-4-醇和取代的黄烷酮的还原,随后进行由S它们中的一些Ñ在甲醇2类型的酸催化,以提供4- methoxyflavans。这些化合物的立体化学由1 H和13 C NMR数据确定。黄烷-4-醇和4-甲氧基黄烷已被解析为对映体,其被评估为抗癌药。
