Ethenylpyrazines and substituted pentylpyridines are potent Β―avouring materials. For a more detailed evaluation of their sensory properties, we synthesized 2-ethenyl-3-ethylpyrazine (1), 2,3-diethenyl-5-methylpyrazine (2), 2-prop-2-enylpyrazine (3), 5-ethenyl-2-methoxy-pyrazine (4), 3-ethenyl-2-etho

β¦ Synopsis
AbstractΓThe liquid odorants (R)-6 and (R)-7 and their corresponding crystalline model substances (R)-8 and (R)-13 were synthesized. Based on the X-ray analyses of (R)-8 and (R)-13, geometries for (R)-6 and (R)-7 were determined using semiempirical calculations.
