Activator-free reactions of carboxylic ortho esters with cyclic β-diketones

The reaction mechanisms of cyclic 1,3-diketones with trialkyl orthoformates and trimethyl orthoacetate in the absence of activators were theoretically and experimentally studied. The reactions proceed via C-C-coupling of the ionized forms of the reactants giving dialkyl acetals, which further transform into vinyl ethers. The reactions of the latter with ortho esters afford aldehydes (ketones). Related 2-acetylcyclopentanone reacts with trimethyl orthoacetate under argon to form a mixture of methyl enol ethers, whereas in the presence of air oxygen dimethyl glutarate is formed.

2--1,3-dicarbonyl compounds were synthesized as photosynthetic electron transport (PET) inhibitors because of their structural resemblance to the potent new PET inhibitors "cyanoacrylates".Their functionalities were different f
