A Mixture of (3S,6R)- and (3R,6R)-3-methyl-6-(1-methylethenyl)dec-9-enyl acetate (1a and 1b, respectively)-1a being a pheromone of the California red scale - is synthesized in 14 steps from (+)-(R)-limonene (4). The key step is the reductive vitamin-B12-catalyzed coupling of (R)-5-(2-iodoethyl)-6-mehtylhept-6-en-2-one ethylene acetal (8) and methyl crotonate (3).
