  摘要 我们打算通过脯氨酸多壁碳纳米管将脯氨酸作为均相催化剂转化为非均相催化剂，以通过简化分离，催化经济性，可重复使用性等方式提高脯氨酸作为催化剂的效率。为了实现这些目标，我们勾勒了脯氨酸-MWCNT催化剂并进行了表征通过不同的分析（例如FT-IR，SEM，EDX，CHNS）进行分析。研究了这种非均相催化剂的效率，并与脯氨酸均相催化剂在曼尼希反应中的效率进行了比较。结果证明了立体选择性，易于分离和可重用性方面的改进。 图形摘要 这项工作代表了一种高效简单的方法来制备脯氨酸多壁碳纳米管，将其作为非均相有机纳米催化剂。脯氨酸MWCNT的特征在于不同的分析。Pro-MWCNTs的效率和催化活性已在曼尼希反应中进行了研究，与母体脯氨酸催化剂相比，非对映选择性，中等对映选择性，良好的重用性和高收率。

  A double axially chiral bisphosphorylimide has been demonstrated to be an efficient and highly sterically hindered Bronsted acid in asymmetric three-component Mannich reactions. Optically active syn-beta-amino ketones were obtained in high yields (up to 99%) with excellent diastereoselectivity (99:1) and enantioselectivity (up to 99% ee). A gram-scale reaction was also performed to prove the synthetic application value of this reaction. (c) 2012 Elsevier Ltd. All rights reserved.

  Acylase I from Aspergillus melleus (AMA) displayed catalytic promiscuity towards one-pot asymmetric Mannich reaction in acetonitrile for the first time. AMA showed favourable catalytic activity with good adaptability to different substrates. The activity and stereoselectivity of the enzyme could be improved by adjusting solvent, pH, water content, temperature, molar ratio of substrates and enzyme loading. The enantioselectivities up to 89% ee, diastereoselectivities up to 90:10 dr (syn/anti) and yields up to 82% were achieved. This work offered a novel case of enzyme catalytic promiscuity and a potential synthetic method for organic chemistry. (C) 2014 Elsevier B.V. All rights reserved.
