- Abstract
Thionation of several γ-, δ- and ε-lactones widely used in flavours and fragrances was carried out using three different synthetic procedures. γ-Thionolactones were synthesized via a microwave-assisted procedure, whereas δ- and ε-thionolactones were prepared using Lawesson's reagent or the P4S10-HMDO combination under standard conditions. The synthesized compounds were submitted to an olfactory evaluation: γ-thionolactones offered a large variety of odours related to saffron, mushrooms and fruits, while δ-thionolactones presented a strong character of sulphur with a poor variety of olfactory notes. cis-Jasmone thionolactone, 6-amylthionopyrone, and menthone thionolactone presented very interesting notes of blackcurrant, Tagetes minuta and celery, respectively.
