Synthesis and odour properties of floral smelling compounds.
Synopsis To provide further information on the relationships between chemical structure and floral odour, here we report the synthesis and the odour evaluation of some spirane derivatives, designed as conformational models of our previously described floral odorants. One of the new compounds (5-methyl-benzo[1,3]dioxole-2-spiro-1-cyclohexane), in particular, is endowed with a particularly pleasant odour of white flowers, can be easily prepared from commercial products and is more stable than other odorants of the same class; these characteristics make this odorant suitable for being used as an additive in perfumery and cosmetics.
