Concise synthesis of Cannabisin G

Cannabisin G (1), a naturally occurring lignanamide, was synthesized in 45% overall yield starting from 3-tert-butyl ethyl ferulate (6). An oxidative coupling by potassium ferricyanide in an alkaline media serves as the key step to construct the biphenylb

Nucleophilic reactivity of dehydrodiferulic acid bislactone

Despite reports to the contrary, dehydrodiferulic acid bislactone can readily undergo nucleophilic attack.Silylation affords the disilyl ether-disilyl ester of the corresponding bismethylenesuccinic acid.Slow dissolution of the bislactone in sodium hydrogen carbonate solution affords this parent diacid, characterised as its mono- and dimethyl esters, and by its methylation to bisveratrylidenesuccinic acid, whose anhydride on aerial oxidation yields 6,7-dimethoxy-1-(3',4'-dimethoxyphenyl)naphthalene-2,3-dicarboxylic anhydride.
