    摘要： A compound of the 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 Damascone® molecules, but lack their disadvantageous skin sensitization effects.

    摘要： Encapsulated perfume composition comprising at least one aminoplast core-shell microcapsule dispersed in a suspending medium, the microcapsule comprising a perfume-containing core encapsulated in a shell, said shell comprising a network of cross-linked aminoplast resin, wherein 75-100% of the resin comprises 50-90%, preferably from 60-85%, of a terpolymer and from 10-50%, preferably from 10-25%, of a polymeric stabilizer; the terpolymer comprising:(a) from 20-35 wt %, preferably 22-30% by weight of moieties derived from at least one triamine,(b) from 30-60 wt %, preferably 40-55% by weight of moieties derived from at least one diamine,(c) from 20-35 wt %, preferably 22-30% by weight of moieties derived from the group consisting of alkylene and alkylenoxy moieties having 1 to 6 methylene units, preferably 1 to 4 methylene units and most preferably 1 methylene unit.The encapsulated perfume composition is useful for the storage and dissemination of fragrance in various products, such as laundry products and fabric care products.

    摘要： A method of providing a cooling effect to a product includes the incorporation into the product of at least one compound of the formula I in which m is a number between 0 and 2, X, Y and Z are selected independently from the group consisting of H, halogen, OH, Me, Et, MeO and EtO, and R1, R2 and R3 together comprise at least 6 carbons, selected such that (a) (i) R1 is selected from the group consisting of H, Me, Et, isopropyl and C4-C5 branched alkyl; and  (ii) R2 and R3 are independently selected from the group consisting of Me, Et, isopropyl and Ca-branched alkyl; or (b) any two or all of R1, R2 and R3 together form a monocyclic, bicyclic or tricyclic radical having up to 10 carbons. The compounds confer substantial cooling effects on compositions applied to the skin or taken orally, such as toothpastes, mouthwashes, foodstuffs, beverages, confectionery, tobacco products, skin creams and ointments.

    摘要： A method of making spirogalbanone includes the steps of: (a) subjecting ethynylspirodecanol to a Rupe rearrangement to give a compound of the formula I (b) converting the compound of (a) to a C1-C4 alkyl acetal; (c) subjecting the acetal to a trans-acetalisation reaction with allyl alcohol in the presence of a mild acid catalyst; (d) heating the product of (c) in the presence of an acid catalyst to give an allylenolether; and (e) subjecting the product of (d) to a Claisen rearrangement to give spirogalbanone. The method affords an easier and more efficient method of preparation.

    摘要： A process of converting a carbon-carbon double bond on a substrate into a cyclopropane ring, which method comprises the step of treating the substrate with a N-alkyl-N-nitroso compound, a transition metal catalyst and an aqueous base, wherein the N-alkyl-N-nitroso compound is formed by reacting an alkyl amine with an alkali metal nitrite in the presence of a mono-basic or di-basic acid, or a mixture thereof, and wherein the N-alkyl-N-nitroso compound is not distilled before it is mixed with the substrate, catalyst and base.
