Janus bases are heterocyclic nucleic acid base analogs that present two different faces able to simultaneously hydrogenbond to nucleosides that form Watson–Crick base pairs. The synthesis of a Janus‐AT nucleotide analogue, NJAT, that has an additional endocyclic ring nitrogen and is thus more capable of efficiently discriminating T/A over G/C bases when base‐pairing in a standard duplex‐DNA context
