The efficient synthesis, antiviral activity, and duplex-stabilizing properties of both isomers of the 2'-fluoro analogue of Northern methanocarbathymidine (N-MCT), 2 and 3, are reported. We show that 2'-F incorporation on the N-MCT scaffold has a strong stabilizing effect on duplex thermal stability. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
