Originally limited to dialkylamino methylenation, the application of Mannich reaction has been expanded much further in recent years to a wide variety of monosubstituted amines, amine equivalents and amides. In addition, a variety of Aza-Mannich and Mannich-Michael methodologies have emerged.

最初该反应的应用范围仅局限于二烷基胺亚甲基化反应，近年来才得到了长足的发展，其研究范围扩展到单取代的胺、胺的类似物以及酰胺等化合物，并发展形成Aza-Mannich和Mannich-Michael等复合Mannich反应。

The results showed that the treatment with spermidine promoted the activities greatly of SOD、POD and photosynthetic intensity but reduced the stomatal resistance to some extent ...

结果表明，亚精胺处理大大提高玉米幼苗中SOD、POD的活性以及光合强度，适当减小气孔阻力，故亚精胺可以提高玉米幼苗的抗旱性。

Replacing DETA with PIP, a new three dimensional compound 3 issynthesized and the 3D anionic framework of compound 3 is constructed from twodistinct motifs, a one-dimensional tancoite chain and a single 4-ring (S4R) unit,which contains four intersecting channels running throughout the structure as 8,12-member ring channels along to the a axis and 12-member ring channels along theb and c axis, respectively.
