Nuc 'em: A variety of nucleic acids can be catalytically alkylated with rhodium-carbenoids generated from diazo compounds in aqueous buffer through an NH insertion process (see scheme; MES=2-(N-morpholino)ethanesulfonic acid). The method specifically targets unpaired bases such as those present in single strands, turn regions, and overhangs while leaving double-stranded sequences untouched.
