  • Process for preparing &bgr;-ketoester fragrance pro-accords from 1,3-dioxan-4,6-diones
    Patent number: 6500797
    Abstract: The present invention relates to methods for preparing &bgr;-ketoester fragrance pro-accords from activated acyl units, 1,3-dioxan-4,6-diones and fragrance raw material alcohols. The first step involves contacting an activated acyl unit, preferably an acid chloride, with a 1,3-dioxan-4,6-dione, an example of which is Meldrum's acid, to form a 2-acyl 1,3-dioxan-4,6-dione which is then reacted with a fragrance raw material alcohol to form the final &bgr;-ketoester fragrance pro-accord. The resulting &bgr;-ketoester fragrance pro-accords are suitable for use in laundry detergent, personal care, and other formulations wherein aesthetic fragrance materials are employed.
