Gold(I)-Catalyzed Cyclization for the Synthesis of 8-Hydroxy-3- substituted Isocoumarins: Total Synthesis of Exserolide F

A highly regioselective gold(I)-catalyzed 6-endo-dig cyclization of 2,2-dimethyl-5-(alkynyl)-4H-benzo[d][1,3]dioxin-4-ones for the synthesis of 8-hydroxy-3-substituted isocoumarins is described. Key features of the reaction include the broad substrate scope, scalability, and tolerance for protecting groups. The synthetic utility of this novel method is demonstrated by the first total synthesis of exserolide F, an isocoumarin-containing polyol natural product.

Inhibition of the enzymes in the leukotriene and prostaglandin pathways in inflammation by 3-aryl isocoumarins

The biosynthesis of leukotrienes in one of the arachidonic acid pathways and PGE2in the other by 5-LOX and mPGES1 respectively, play pivotal roles in augmenting inflammatory responses. PGE2is known to participate in cancer pathologic

Synthesis of 3-arylisocoumarins by using acyl anion chemistry and synthesis of thunberginol A and cajanolactone A

A new strategy for the synthesis of 3-arylisocoumarins and 8-hydroxy-3-arylisocoumarins was investigated by using acyl anion chemistry for the initial C-C bond formation. The obtained keto esters and keto lactones as intermediates underwent based-promoted intramolecular cyclization to afford 3-arylisocoumarins in good yields. The developed methodology was applied for the synthesis of the important natural products thunberginol A and cajanolactone A.

Synthesis of 3-arylisocoumarins, including thunberginols A and B, unsymmetrical 3,4-disubstituted isocoumarins, and 3-ylidenephthalides via iodolactonization of methyl 2-ynylbenzoates or the corresponding carboxylic acids

3-Aryl-4-iodoisocoumarins, which were readily and efficiently prepared by regioselective iodolactonization of methyl 2-ynylbenzoates or the corresponding carboxylic acids, were used as precursors either to 3-arylisocoumarins, including naturally-occurring
