Lactone compounds which can be used as antioxidant agents in pharmaceutical, cosmetic or food compositions and their method of preparation

The subject of the present invention is specific lactone compounds which can be used as antioxidant agents in pharmaceutical or cosmetic compositions or in food products, the said compounds containing a naphthalene ring onto which two lactone units are gr

Synthesis of pulvinic acid and norbadione A analogues by Suzuki-Miyaura cross-coupling of benzylated intermediates

Pulvinic acid and norbadione A analogues can be prepared by Suzuki-Miyaura cross-coupling of functionalized aryl-boronic esters with appropriate vinyl inflates, in which the hydroxy functions are protected either with methyl or benzyl groups, the latter being cleaved in a more reliable fashion at the end of the synthetic sequence.

Synthesis of natural pulvinic acids based on a '[3+2] cyclization-Suzuki cross-coupling' strategy

A number of pulvinic acid natural products were prepared based on Suzuki cross coupling reactions of α-hydroxy-γ-alkylidenebutenolides which are readily available by cyclization of 1,3-bis-silyl enol ethers with oxalyl chloride. The formal total synthesis

Norbadione A: Synthetic approach to the bis(pulvinic acid) moiety and cesium-complexation studies

A permethylated analogue 1 of the mushroom pigment norbadione A was synthesized through a double Suzuki-Miyaura coupling of 1,7-diboronated naphthalene 2 and triflate 3. ESI-MS studies showed similar constants for the formation of the complexes of the nor
