TL;DR: In this article, a mixture of the corresponding aldehydes, their acetals, and methyl carboxylates were formed under similar conditions from the salts of primary nitro compounds.
Abstract: Alkaline salts of aci-forms of secondary nitro compounds, viz., β-nitropropylbenzene, nitrocyclohexane, 5-nitroheptan-2-one, and methyl-4-nitrohexanoate, were selectively or predominately oxidized into the corresponding ketones and their ketals under conditions of undivided amperostatic electrolysis in methanol. Mixtures of the corresponding aldehydes, their acetals, and methyl carboxylates were formed under similar conditions from the salts of primary nitro compounds, viz., 1-nitrohexane, nitromethylbenzene, and β-nitroethylbenzene.

TL;DR: In this paper, a method for the synthesis of n-(3-acyloxypropyl)-substituted six- to thirteen-membered alkan-nolides was developed.
Abstract: A new method for the synthesis of n-(3-acyloxypropyl)-substituted six- to thirteen-membered alkan-n-olides was developed. The method is based on the H2SO4-catalyzed reactions of oxabicycloalkenes, obtained from 2-(3-acetoxypropyl)cycloalkanes, with H2O2 and formic or acetic acid. The method includes the subsequent transformations of oxabicycloalkenes into bicyclic hydroperoxides, peroxy ethers, and, at the final stage, into target lactones formed in 56—71% yields. These transformations are carried as a one-pot reaction.
