A new class of tricyclic nucleosides in which the aglycon has a linear [6:5:6] geometry has been synthesized using certain pyrrolo[2,3-d]pyrimidine nucleosides as the starting materials. An adenosine-adenosine analogue (12) has been prepared from 6-aminotoyocamycin using two different synthetic routes. An adenosine-guanosine analogue (4) and several adenosine-6-mercaptopurine ribonucleoside-type tricyclic
