Eco-friendly, highly efficient and large-scalable Henry reactions of aromatic aldehydes and nitroalkanes catalyzed by glucoamylase from Aspergillus niger (AnGA) are described. The reactions were carried out at 30 °C in the mixed solvents of ethanol and water, and the corresponding β-nitro alcohols were obtained in yields of up to 99%. Only 3 mg of enzyme was sufficient to catalyze the reaction of 1 mmol aldehydes. The natural activity and promiscuous activity of AnGA were compared under different conditions. Experiments demonstrated that the product of the Henry reaction could inhibit AnGA at 80 °C. This enzymatic Henry reaction showed a broad substrate scope, and could be facilely enlarged to gram scale. The possible mechanism was also discussed.

The first examples of highly effective Henry reactions between nitroalkanes and aldehydes or trifluoromethyl ketones that proceed under catalyst-free and additive-free conditions, in a recyclable tap water medium, and at room temperature are reported. This process tolerates a broad range of aldehydes and trifluoromethyl ketones to give a series of β-nitro alcohol products in excellent yields. Such
The alpha-hydroxy phosphonates have been synthesized using simple, inexpensive, and commonly available Ba(OH)(2)center dot 8H(2)O at room temperature and quantitative yields were obtained in just 15 min for most of the reactions. On applying the same reaction condition to aqueous mediated Henry reaction, 2-nitroalkanols were obtained in good to excellent yield within 15 min. (C) 2012 Elsevier B.V. All rights reserved.
