A dual-catalytic strategy for the synthesis of enamides and enecarbamates directly from easily accessible and inexpensive amino acids has been realized. This mild and efficient protocol makes use of an organic photoredox catalyst and a cobaloxime catalyst to achieve decarboxylative elimination using hydrogen evolution to drive the oxidation. Thus, the reaction occurs without a stoichiometric oxidant
The present invention concerns groups of compounds derived from tunicates of the Synoicum species, as well as to pharmaceutical compositions comprising these compounds, and uses thereof. Extracts from tunicates show selective toxicity against several different cancer cell lines in the NCI 60 cell line panel. These compounds are useful in the effective treatment of cancers, particularly malignant melanomas, colon cancer, and renal cancer cell lines.
