The present invention relates to a fragrance composition comprising ionic liquids for enhanced evaporation of the perfume raw materials. The invention also relates to methods of use of the fragrance compositions for perfuming suitable substrates, particularly skin and hair.
dihydroxylation of a series of functionalised polyenes is described. Under acidic conditions, the osmateester derivatives obtained from oxidation with OsO4/TMEDA undergo an intramolecular cyclisation reaction forming functionalised tetrahydrofurans with high stereoselectivity and in good yield. The generality of this method is illustrated with an application to the synthesis of a bis-tetrahydrofuran ring system
