Synthesis and characterization of oligodeoxynucleotides containing a novel tetraazabenzo[cd]azulene:naphthyridine base pair

The synthesis and thermal stability of oligodeoxynucleotides (ODNs) containing 4-amino-2,3,5,6-tetraazabenzo[cd]azulen-7-one nucleosides 5 (BaON) with the aim of developing new base pairing motif is described. The tricyclic nucleoside 5 was prepared starting with the 7-deaza-7-iodopurine derivative 1 via a palladium catalyzed cross-coupling reaction with methyl acrylate, followed by an intramolecular cyclization. The resulting nucleoside was incorporated into ODNs, and the base pairing property of the BaON: NaNO (2-amino-7-hydroxy-1,8-naphthyridine nucleoside) pair in the duplex was evaluated by a thermal denaturation study. The melting temperature (T-m) of the duplex containing the BaON: NaNO pair showed a higher value than that of the duplexes containing the adenine: thymine (A:T) and the guanine: cytosine (G:C) pairs, however it was lower than that of the ImO(N): NaNO (ImO(N) = 7-amino-imidazo[5′,4′:4,5]pyrido[2,3-d]pyrimidin-4(5H)-one nucleoside) pair. A temperature-dependent H-1 NMR study revealed that the H-bonding ability of BaON was lower than that of ImO(N), which would explain why the BaON: NaNO pair was less thermally stable than the ImO(N): NaNO pair.

Enantioselective Total Synthesis of (-)-Finerenone Using Asymmetric Transfer Hydrogenation

(-)-Finerenone is a nonsteroidal mineralocorticoid receptor antagonist currently in phase III clinical trials for the treatment of chronic kidney disease in type 2 diabetes. It contains an unusual dihydronaphthyridine core. We report a 6-step synthesis of (-)-finerenone, which features an enantioselective partial transfer hydrogenation of a naphthyridine using a chiral phosphoric acid catalyst with a Hantzsch ester. The process is complicated by the fact that the naphthyridine exists as a mixture of two atropisomers that react at different rates and with different selectivities. The intrinsic kinetic resolution was converted into a kinetic dynamic resolution at elevated temperature, which enabled us to obtain (-)-finerenone in both high yield and high enantioselectivity. DFT calculations have revealed the origin of selectivity.
