The Henry (nitroaldol) reaction is one of the most important methods for carbon–carbon formation. The adducts may be transformed into valuable building blocks. β-Nitroalkanols are particularly important precursors in the synthesis of nitro alkenes, β-amino alcohols and α-nitro ketones.1-5 Nitro alkenes have proved to be useful intermediates, which behave both as electron-deficient alkenes and as heterodienes in Diels–Alder reactions,6-7 while α-nitro ...
