The Protection of Thymine and Guanine Residues in Oligodeoxyribonucleotide Synthesis

Thymidine is converted in four steps into its crystalline 4-O-phenyl derivative (14b) in 72percent overall yield. 2'-Deoxyguanosine is converted in five steps into its 6-O-(2-nitrophenyl)-2-N-phenylacetyl and crystalline 6-O-(3,5-dichlorophenyl)-2-N-phenylacetyl derivatives in ca. 39 and 42percent overall yields, respectively.Compounds (14b), (19a), and (19b) are converted into the corresponding crystalline 5'-O-(9-phenyl-9H-xanthen-9-yl) derivatives (15), (20a), and (20b), respectively.The actions of N1,N1,N3,N3-tetramethylguanidinium 2-nitrobenzaldehyde oximate, 80percent acetic acid, potassium carbonate in aqueous dioxane, pyridine, and triethylammonium toluene-p-thiolate on (14b), (19a), and (19b) have been investigated.
