Ethyl 2-furoate

Ethyl furoate (2-Furancarboxylic acid, ethyl ester) COOC2H5... 

Ethyl furoate undergoes a Friede 1-Crafts condensation with tertiary chlorides in carbon disulfide solution. The free alkylfuroic acids are oxidized by alkaline potassium permanganate to trialkylacetic acids. Dimethylethylacetic acid (65%) and 1-methyl-l-cyclohexylcarboxylic acid (44%) have been prepared in this manner. ...

Products and Uses There are 4000 ingredients in cigarettes. Additives include yeast, wine, caffeine, beeswax, and chocolate. Other ingredients, or by-products, include ammonia, angelica extract (which is a carcinogen in animals), benzene, benzopyrene, butone, cadmium, cyanide, DDT, ethyl furoate, lead formaldehyde, methoprene (insecticide), napthalene, and tars, and so on. 

A variety of 2-substituted-3-pyridinols can be prepared by well-known methods. For example, diarylmethyl 2-lliryl ketones are prepared in good yield from ethyl fliroate and diarylmethanes using KNH2 or NaNHj in liquid ammonia and are conveniently converted to XII-279. p-Chlorobenzyl 2-furyl ketones, which can be converted to XU-280, can be prepared from p-chlorophenylacetonitrile and ethyl furoate by condensation in the presence of alkoxide followed by hydrolysis and decarboxylation. 2-Pyrryl ketones are also formed in the last step. Several 2-furyl ketones are cleaved under these reaction conditions and do not give 3-pyridinols. ...
