β-Nitroalcohols can be efficiently obtained with the help of AmberlystA-21, as heterogeneous basic catalyst, with or without solvent. This method is farsuperior to the heterogeneouscatalysts previously reported for the nitroaldol (Henry) reaction, in fact it gives higher yields with primary and secondary nitroalkanes, the formation of by-products such as nitroalkenes is avoited even if aromatic

Dimethylnitro alcohols are constructed in a one-pot process from benzylic halides and 2-nitropropane. The use of tetrabutylammonium fluoride (TBAF) as the promoter is essential for this tandem Hass-Bender/Henry reaction to proceed. (c) 2005 Elsevier Ltd. All rights reserved.
