A compound of Formula (I) wherein R1 represents a C3 to C20 hydrocarbon group derived from a fragrant alcohol of formula R1OH or from a fragrant aryl aldehyde or ketone of Formula (II), wherein: R2 is, independently, hydrogen atom, hydroxyl group, acetoxy group, -O(C=O)CH(CH3), optionally substituted C1-C6 alkyl group or C1-C6 alkoxy group, wherein any two of R2 may form an optionally substituted 5 or 6 membered ring, and R1 represents a radical derived from a fragrant alcohol of formula R1OH or from a fragrant aldehyde or from a fragrant aryl aldehyde or ketone of formula (II). The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols or aldehydes.

supporting information; experimental part, p. 4204 - 4207 (2010/12/24)
β-Lithiooxyphosphonium ylides, generated in situ from aldehydes and Wittig reagents, react readily with halomethyl esters to form trisubstituted Z-allylic esters. The methodology was applied to a total synthesis of the geranylgeraniol-derived diterpene (6S,7R,Z)-7-hydroxy-2-((E)-6-hydroxy-4- methylhex-4-enylidene)-6,10-dimethylundec-9-enyl acetate (12).

, p. 9862 - 9863 (2008/02/13)
Together with the improved synthesis of the diene unit 15 of methyl sarcophytoate (1), a biscembranoid marine natural product, the asymmetric total synthesis of 1 was achieved by the thermal Diels-Alder reaction between the dienophile unit, methyl sarcoat
