摘要

We describe the design, preparation, and properties of two key building blocks of a size- expanded genetic system. Nucleoside analogues of the natural nucleosides dA and dT are reported in which the fusion of a benzo ring increases their size by ca. 2.4 Å. The expanded dA analogue (dxA), having a tricyclic base, was first reported by Leonard nearly three decades ago. We describe a shortened and more efficient approach to this compound. ...
