We describe two approaches for the synthesis of 2′-C-β-methyl-2′-deoxyguanosine (3) via 2′-radical deoxygenation. One approach starts from 1,3,5-tri-O-benzoyl-α-d-ribofuranose (6) and gives 3 in 11 steps with 9.7% overall yield. The second approach starts from guanosine and gives 3 in 8 steps with 23% overall yield.
我们描述了通过2'-自由基脱氧合成2' - C -β-甲基-2'-脱氧鸟苷(3)的两种方法。一种方法是从1,3,5-三-O-苯甲酰基-α - d-核呋喃糖(6)开始,分11步给出3步,总产率为9.7%。第二种方法从鸟苷开始,分8步进行3步,总收率23%。
