An efficient one-to-one coupling reaction of atmospheric pressure carbon dioxide with 1,3-dienes is realized for the first time through PSiP-pincer type palladium-catalyzed hydrocarboxylation. The reaction is applicable to various 1,3-dienes including easily available chemical feedstock such as 1,3-butadiene and isoprene. This protocol affords a highly useful method for the synthesis of β,γ-unsaturated carboxylic acid derivatives from CO2.
(E)-4,8-DIMETHYL-1,3,7-NONATRIENE AND (E,E)-4,8,12-TRIMETHYL-1,3,7,11-TRIDECATETRAENE, TWO UNUSUAL HYDROCARBONS FROM CARDAMOM OIL

The identification of two new natural products, (E)-4,8-dimethyl-1,3,7-nonatriene 1 and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene 3 is reported.These unusual C11 and C16 hydrocarbons were isolated from essential oil of Elettaria cardamomum Maton var. miniscula Burkhill (Zingiberaceae) and their structures confirmed by synthesis.
