For clarity, and not by way of limitation, the detailed description is divided into the following subsections:
1. Definitions;
2. Fragrance Compound;
3. Fragrance Compositions; and
4. Use of Fragrance Compositions in Consumer Products.
The terms used in this specification generally have their ordinary meanings in the art, within the context of this disclosure and in the specific context where each term is used. Certain terms are discussed below, or elsewhere in the specification, to provide additional guidance to a person of ordinary skill in the art describing the compounds, compositions and methods of the disclosure and how to make and use them.
As used herein, the use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification can mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” a plurality, and “one or more than one.” Still further, the terms “having,” “including,” “containing” and “comprising” are interchangeable and one of skill in the art is cognizant that these terms are open ended terms.
The term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, “about” can mean within 3 or more than 3 standard deviations, per the practice in the art. Alternatively, “about” can mean a range of up to 20%, preferably up to 10%, more preferably up to 5%, and more preferably still up to 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, preferably within 5-fold, and more preferably within 2-fold, of a value.
As used herein, the term “isomers” refers to different compounds that have the same molecular formula but differ in arrangement and configuration of the atoms. Also, as used herein, the term “stereoisomer” refers to any of the various stereo isomeric configurations which can exist for a given compound of the presently disclosed subject matter and includes geometric isomers. It is understood the compound of the present disclosure contains double bonds, where the substituents can be E or Z configuration. Also, as used herein, the terms “constitutional isomers” refers to different compounds which have the same numbers of, and types of, atoms but the atoms are connected differently.
As used herein, the term “fragrance composition” refers to a mixture comprising one or more fragrance compounds, in any of their forms, and one or more solvents or perfuming co-ingredients. As known in the art, a fragrance composition contains one or more fragrance compounds in order to impart an olfactory note to the consumer product formulation (e.g., a household cleaner, perfume, or other consumer product) to which it is added. In one embodiment, the fragrance composition contains two or more fragrance compounds which, collectively and in combination with the solvent to which they are added, impart an intended olfactory note (e.g., a hedonically pleasing “tropical” note) to a human in close proximity to the fragrance composition. In general terms, perfuming co-ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpene hydrocarbons, nitrogenous or sulphurous heterocyclic compounds and essential oils of natural or synthetic origin, and are known to perfumers of ordinary skill in the art. Many of these ingredients are listed in reference texts such as S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, N.J., USA or any of its more recent versions, each of which are hereby incorporated by reference in their entireties.
As used herein, the term “accord” refers to a fragrance composition that contains a mixture of two or more different fragrance compounds that creates a specific smell, odor or scent. One or more “accords” can be utilized as part of fragrance composition.
As used herein, the term “consumer product” or “end product” refers to composition that is in a form ready for use by the consumer for the marketed indication. A solvent suitable for use in a consumer product is a solvent that, when combined with other components of the end product, will not render the consumer product unfit for its intended consumer use.

The compound of Formula I was synthesized as follows:
Wittig salt cis-3-hexenyltriphenlyphosphonium bromide (62.4 g, 1.1 eq.) was added to a flask equipped with an addition funnel. The flask was then purged and flushed with N2. Anhydrous diethyl ether (360 mL) was added to the salt and a slurry was formed. N-BuLi (2.5M in hexanes, 58.8 ml, 1.1 eq.) was added dropwise at room temperature. The reaction mixture was stirred for 1 hour after complete addition to form the ylide. The reaction mixture was then cooled in a bath of acetone and dry ice slurry at about −35° C. Thiophene carboxaldehyde (15 g, 1 eq.) in 135 mL of anhydrous diethyl ether was added dropwise to the cooled reaction mixture. After addition, the reaction was allowed to warm to room temperature gradually and stirred at room temperature overnight. After this time, the reaction mixture was quenched with sat. NH4Cl, extracted with diethyl ether, washed with brine, dried over MgSO4, and filtered. The filtrate was then concentrated. Diethyl ether was added to the crude product to precipitate most of the triphenyl phosphine oxides that were formed. The suspension was filtered, and the filtrate was concentrated under vacuum. Kugelrohr distillation was then employed to separate the products (as a 50/50 mixture of cis-cis and trans-cis isomers) from the remaining triphenyl phosphine oxides (14.0 g, 57% yield). Odor: green, tomato, violet leaf, geranium. GC/MS(EI): m/z (%) 178(28), 163(6), 149(51), 135(52), 123(15), 110(100), 97(69), 79(39), 65(22), 45 (56). 1H NMR (CDCl3): δ0.09 (t, 3H), 2.08 (m, 2H), 2.89/3.13 (t, 2H), 5.51 (vinyl m, 3H), 6.05/6.48 (vinyl m, 1H), 6.97 (m, 2H), 7.25 (m, 1H).
A berry fragrance composition was prepared from the presently disclosed compound to demonstrate use in a shampoo.
