Neoflavone β-D-glucopyranosides, β-D-galactopyranosides, β-D-xylopyranosides, and α-D-arabinopyranosides were synthesized by Michael condensation of potassium salts of 7-hydroxy-4-arylcoumarins with acetobromosugars followed by deacetylation of the resulting peracetates.
新黄酮β-D-吡喃葡萄糖苷、β-D-吡喃半乳糖苷、β-D-吡喃木糖苷和α-D-吡喃阿拉伯糖苷是通过 7-羟基-4-芳基香豆素的钾盐与乙酰溴化糖的迈克尔缩合反应合成的,然后对生成的过乙酸酯进行脱乙酰化反应。
