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. ...

Nitrogen heterocycles Various cyano-substituted pyridines have been described. They were prepared from 10 and ethyl cyanoacetic ester, and from 10 and acetylenic esters or ketones ". Aromatic aldehydes (e.g. 2-furyl, 4-pyridyl, and 2-thienyl aldehydes) have been condensed with 10 and aromatic ketones to yield 2-amino-3-pyridinecarbonitriles. Benzylidenemalononitrile (43) reacted with 10 in aniline to yield dicyanopyridine 44. ... 

The volatiles of roasted coffee include the aliphatic compounds with different carbonyl compounds, and sulfur containing compounds, and alicyclic compounds containing ketones and aromatic benzenoid compounds. Among the character impact compounds, the (2-furyl)-methanethiol and kahwefuran (2-methyl-3-oxa-8-thiobiocyclo-[3.3.0] octa-l,4-diene) are present in relatively high amounts. The burnt coffee-like character is mostly associated with 2-ethylfuran, IV-ethyl formylpyr-role, thiobutyrolactone, and 2-acetyl-3-methylthiopen [35,37].

The main (key) components of chocolate aroma are Cj carboxylic acids with a sweet smell (2-methylbutyric), lactones (y-lactone with a sweet, peachy aroma), aldehydes (such as isovaleraldehyde with a sharp odour resembling malt), ( )-non-2-enal (with green and tallowy smell), (2 ,4 )-nona-2,4-dienal and (2 ,4 )-deca-2,4-dienal (with oily smell resembling fried foods), ketones, such as oct-l-en-3-one (with the mushroom-like smell), (2 ,5S)- and (2 ,5 )-5-methyl-hept-2-en-4-one (known as filbertone, which has the odour of hazelnuts, 8-204), 2-ethyl-3,5-dimethylpyrazine (with a smell reminiscent of fried potato chips), 2-ethyl-3,6-dimethylpyrazine (with the smell of nuts with earthy tones) and methyl 2-methyl-3-furyl disulfide with meaty and sulfur smell.
