Vinyl ethers can be protonated to generate oxocarbenium ions that react with Me3SiCN to form cyanohydrin alkyl ethers. Reactions that form racemic products proceed efficiently upon conversion of the vinyl ether to an α-chloro ether prior to cya

The present invention is a fragrance precursor of formula I: 1for a fragrant ketone of formula II: 2and a fragrant ester of formula III: 3wherein, R1 to R5 represent independently H, —NO2, linear or branched C1-C6-alkyl, C1-C6-alkenyl, C1-C6-alkinyl or C1-C4-alkoxy, R1 and R2, R2 and R3, R3 and R4, and R4 and R5 may form together one or two aliphatic or aromatic rings, R6 and R7 are independently H, linear or branched C1-C6-alkyl-, C1-C6-alkenyl, C1-C6-alkinyl, and R8 and R9 are the residues of an acid R8-COOH and an alcohol R9OH respectively forming the fragrant ester of formula III. A method for providing an odor by admixing with a product a fragrance precursor as detailed above.
