查询词典 reaction ring

The reaction was assumed to be an electronphilic attack of nitrosonium on imines, resulting a four-member ring intermediate.

推定该反应经历了一个四员环过渡态，在过渡态中通过化学键的断裂与重组生成了相应的重氮盐和芳香醛。

Under the same conditions, activity of thiolphenol is much lower than that of thiols. An electron withdrawing group on the benzene ring can decrease the reaction activity, but an electron donating group on the aliphatic compound can increase it.

在相同的反应条件下，苯硫酚的反应活性明显低于硫醇的反应活性；巯基化合物中吸电子基团会使反应活性降低，而推电子基团会使反应活性提高。

The inhibition of oestrogen synthesis is most readily achieved by inhibiting the final step in the pathway of oestrogen biosynthesis, the reaction which transforms androgens into oestrogens by creating an aromatic ring in the steroid molecule (hence the enzyme's trivial name, aromatase).

oestrogen 综合的抑制被最容易透过在oestrogen biosynthesis的小路抑制最后步骤取得，回应，透过在类固醇分子(因此酵的琐屑的名字，aromatase)内建立一个芳环把雄性激素转变成oestrogens。
