β-Nitro alcohols (nitro aldols) in boiling benzene in the presence of Bu2SnO (20–30 mol.%) under neutral conditions undergo dehydration leading to nitroalkenes.

A method for the stereoselective synthesis of substituted 4aS*,7aS*-hexahydrocyclopenta[c]pyran-3(1H)-one, promising synthon of isoprostanes, has been developed based on the intramolecular dipolar [3+2] cycloaddition of silyl nitronates generated from 6-nitrohex-1-ene derivative.
