An Expedient Total Synthesis of Triciribine.

In the present paper, we report an expedient total synthesis of triciribine, a tricyclic 7-deazapurine nucleoside and protein kinase B (AKT ) inhibitor, in 35% overall yield. Our synthesis route features a highly regioselective substitution of 1--Boc-2-methylhydrazine and a trifluoroacetic acid catalyzed one-pot transformation which combined the deprotection of the -butylcarbonyl (Boc) group and ring closure reaction together to give a tricyclic nucleobase motif.
