Described herein are novel divalent nucleobases that each bind two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone (a genetic recognition reagent, or genetic recognition reagent). In one embodiment, the genetic recognition reagent is a peptide nucleic acid (PNA) or gamma PNA (?PNA) oligomer. Uses of the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.

have been substituted by O-, S-, N-, and C-centered nucleophiles under solvent-free reaction conditions. The products are generated in good to excellent yields. para-Toluenesulfonic acid exhibits the best catalytic activity compared to other Brønstedacids. Experimental observations suggest that the reaction proceeds through the intermediacy of the keto tautomer of naphthol. Nucleophilic addition to
在无溶剂反应条件下,萘酚和互变异构酚衍生物的羟基已被O-,S-,N-和C中心的亲核试剂取代。产生的产品良率极佳。与其他布朗斯台德酸相比,对甲苯磺酸显示出最佳的催化活性。实验观察表明该反应通过萘酚的酮互变异构体的中间体进行。亲核加成到羰基上,然后除去水,得到所需产物。本方法提供了对取代的萘[2,1- b ]呋喃衍生物的访问。使用N生成的产品以中心为中心的亲核试剂可以进一步转化为重要种类的有机分子,例如苯并咔唑和咪唑衍生物。

Described herein are divalent nucleobases that each binds two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone, such as in a γ-peptide nucleic acid (γPNA). Also provided are genetic recognition reagents comprising one or more of the divalent nucleobases and a nucleic acid or nucleic acid analog backbone, such as a γPNA backbone. Uses for the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.
