Effects of Structural Modifications on the Odour of Jasmone Analogues

The odour of 2-alkylcyclopentanones can be radically affected by substituents on the first or second carbon atoms of the side chain, substituents further along the chain having a much lesser effect on the odour character. It is postulated that these effects could be rationalised in terms of obstruction of the carbonyl group by a substituent on the first carbon of the side chain or disruption of the side chain conformation by one on the second position

Unsaturated Components in the Essential Oil of Anthemis nobilis L. (Roman Chamomile)

French authors recently presented their analytical findings on the oil using the negative chemical ionization technique in mass spectrometry. They tracked the GLC profile of the complete oil with the mass numbers of the quasi-molecular ions [M-H]- in combination with the carboxylate anion RCOO-. Thereby inter alia the presence of five esters derived from methacrylic or crotonic acid was reported, however, without giving definite structural assignments for the individual components. The same holds for eight esters of the angelate or tiglate type, respectively. We have worked in a more traditional way and wish here to present the results concerning some of these methacrylates, crotonates, angelates and tiglates. All esters mentioned by us have proved by comparison with authentic synthetically prepared samples.
