Abstract

Here we describe a preliminary investigation on the ability of natural keratin to catalyze the nitroaldol (Henry) reaction between aldehydes and nitroalkanes. Both aromatic and heteroaromatic aldehydes bearing strong or moderate electron-withdrawing groups were converted into the corresponding -nitroalcohol products in both DMSO and in water in the presence of tetrabutylammonium bromide (TBAB) as ...
