      Research Abstract	
              Didemnaketals are rare terpenoid class reported only in the marine ascidian Didemnum species. They possess important biological activities like HIV-1 protease inhibitor, protein kinase inhibition, antimicrobial, antiproliferative, and cytotoxic. A compilation of new naturally occurring didemnaketals reported during 1991–2014 is provided with available physical and spectral data: mp,[a]D, UV, IR, 1H and 13C NMR as well as biological activities and references.
