Title (EN) COMPOUNDS
(FR) COMPOSÉS
Abstract:
(EN) A compound of formula (I), in which, independently, R1 is selected from H and methyl; R2 is selected from H, and methyl; R3 is selected from H, methyl and ethyl; R4 is selected from H, methyl and ethyl; or R3 and R4 together form a ring in which n is 1 or 2. The compounds have the characteristic desirable odour qualities of the DamasconeTM molecules, but lack their disadvantageous skin sensitization effects.
(FR) La présente invention concerne un composé de formule (I), dans lequel, indépendamment, R1 est sélectionné parmi H et un groupe méthyle; R2 est sélectionné parmi H, et un groupe méthyle; R3 est sélectionné parmi H, un groupe méthyle et éthyle; R4 est sélectionné parmi H, un groupe méthyle et éthyle; ou R3 et R4 conjointement forment un cycle dans lequel n a la valeur de 1 ou 2. Les composés présentent les qualités d'odeur souhaitables caractéristiques des molécules de damasconeTM, mais ne possèdent pas leurs effets négatifs de sensibilisation de la peau.
