Didemnilactones A and B and neodidemnilactone three new fatty acid metabolites isolated from the tunicate Didemnum moseleyi (Herdman)
摘要:
Three new fatty acid metabolites didemnilactones A (1) and B (2) and neodidemnilactone (3) were isolated from the tunicate Didemnum moseleyi (Herdman). Their structures including absolute stereochemistry were established on the basis of spectral studies and chemical synthesis. Didemnilactones exhibited inhibitory activity against lipoxygenase and weak binding activity to leukotriene B-4 receptors.

The present invention relates to the field of organic synthesis and more precisely to a process for the synthesis of an unsaturated aldehyde or ketone by oxidation of the corresponding alcohol. Said oxidation is characterized in that it is performed by means of a hypochlorite salt and a catalytic amount of a N-(2,2,6,6-tetraalkyl-4-piperidinyl-N-oxyl)-2-amino-1,3,5-triazine derivative, preferably a N-oxyl derivative of the polymers known under the trademark Chimassorb® 944 or 2020.
