Abstract:
An efficient process for preparing (9E,11Z)-9,11-hexadecadienal of formula (4) is provided. The process includes at least steps of: conducting a nucleophilic substitution reaction between an (8E,10Z)-8,10-pentadecadienyl magnesium halide derived from an (8E,10Z)-1-halo-8,10-pentadecadiene of (1): and an orthoformate ester (2) to thereby prepare a (9E, 11Z)-1,1-dialkoxy-9, 11-hexadecadiene (3): and hydrolyzing the (9E, 11Z)-1,1-dialkoxy-9,11-hexadecadiene (3) to obtain (9E, 11Z)-9,11-hexadecadienal (4).

Claim (Index 1):
A process for preparing (9E,11Z)-9,11-hexadecadienal of the following formula (4): said process comprising at least steps of:\n conducting a nucleophilic substitution reaction between an (8E,10Z)-8,10-pentadecadienyl magnesium halide derived from an (8E,10Z)-1-halo-8,10-pentadecadiene of the following general formula (1): \n wherein X is a halogen atom, and an orthoformate ester of the following general formula (2): wherein R may be the same or different at each occurrence and is an alkyl group having 1 to 6 carbon atoms, to thereby prepare a (9E,11Z)-1,1-dialkoxy-9,11-hexadecadiene of the general formula (3): wherein R may be the same or different at each occurrence and is an alkyl group having 1 to 6 carbon atoms; and\n hydrolyzing the (9E,11Z)-1,1-dialkoxy-9,11-hexadecadiene (3) to obtain (9E,11Z)-9,11-hexadecadienal of the formula (4) shown above.
