1)  diimide reduction
二亚胺还原
2)  reduction of imines
亚胺还原
1.
Catalytic enantioselective reduction of imines represents one of the moststraightforward and efficient methods for the preparation of chiral amines, animportant intermediate for the synthesis of natural products and chiral drugs.
文献研究认为,除N-甲酰基外,分子内含有芳香酰胺是能催化亚胺还原的有机小分子路易斯碱催化剂具有较高对映选择性的必要条件,我们研究发现N-甲酰脯氨酸非芳香酰胺类催化剂(包括结构简单的C_2-对称型脯氨酰胺类催化剂),对N-芳基酮亚胺的还原可获得达86%的对映选择性,远高于同类芳香酰胺催化剂,证明N-甲酰非芳香酰胺类路易斯碱催化剂在亚胺还原中也能得到高的对映选择性。

2.
Racemic 5-methoxy-2-(N-propylamino)tetralin was subsequently prepared by a reductive amination reaction using n-propylamine and the racemic mixture successfully resolved to give the chiral compound (-)-5-methoxy-2-(N-propylamino)tetralin, which was finally converted to (-)-5-hydroxy-2-(N-propylamino) tetralin via a demethylation reaction.

补充资料:二亚胺还原
分子式:
CAS号:

性质:以二亚胺(NH=NH)为还原剂的有机化合物的还原反应。二亚胺为选择性很好的还原剂,能有效地还原烯键、炔键、氮氮三键等非极性的不饱和键,而极性不饱和键如C=N,C三N,NO2,S=O则不受影口向。如:NO2—C6H4—CH=CHCOOHNO2C6H4CH2CH2COOH反应是经过一个环状的过渡态,发生氢的转移和氮气的释放。二亚胺还原的操作比较简单,收率也比较高,在有机合成上有一定的价值。
