During the synthetic pursuit of guanosine (triG) and xanthosine (triX) tricyclic nucleosides analogues, an interesting side product was discovered. In an effort to uncover the mechanistic factors leading to this result, a series of reaction conditions were investigated. It was found that by varying the conditions, the appearance of the side product could be controlled. In addition, the yield of the
