Abstract
A compound of formula 1 wherein the symbol R′ represents a linear or branched, unsaturated or saturated hydrocarbon group having from 1 to 5 carbon atoms; R1, R2, R3, R4 and R5 represent, independently of each other, a hydrogen atom, a methyl, an ethyl or a methoxy group; R6 and R7 represent, independently of each other, a hydrogen atom, a methyl, ethyl, n-propyl or iso-propyl group; and wherein R5 and R6, when taken together with the carbon atoms to which they are bound, may form a six-membered ring, is useful as perfuming ingredient for the preparation of perfuming compositions and perfumed products, to which it imparts odor notes of the floral and indol type without coloring problems in the final product.
