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.

First total synthesis of natural products cajanolactone A and cajanonic acid A

First total synthesis of cajanolactone A and cajanonic acid A has been achieved through steps of anion-anion condensations, cyclization, Williams etherification, selective demethylation, 1,3-sigmatropic rearrangement and hydrolysis. This work provides an efficient method for future cajanonic acid A derivatives synthesis.
