2-substituted succinate diesters were obtained by two key steps: (i) Michael addition of a nitroalkane to the appropriate enedione derivative under basic conditions (DBU), with the concomitant elimination of nitrous acid, and (ii) selective reduction of the obtained enone with nickelboride, in methanol/THF. In this context the nirtoalkane acts as an alkyl anion synthon. By this method trimethyl tricarboxylates

ω-Nitroalcohols have been prepared by a new and efficient chemio- and regioselectivereductive cleavage performed on 2-nitrocycloketones with sodium borohydride in acetonitrile / water. This reaction opens a more practical and convenient route to the synthesis of spiroketals.

Abstract (Z)-11-Hexedecenal 1a and (Z)-13-octadecenenal 2a, components of the sex attractant pheromone of Chilo supressalis, have been synthesized as their ethylene acetals 1b and 2b from cyclododecanone 3, through intermediacy of the C12 ω functionalized acetals 8 and 12.
