A general access to 4-substituted 6-arylpyrrolo[2,3-d]pyrimidine (6-substituted 8-aryl-7-deazapurine derivatives) was developed based on iridium-catalyzed C–H borylations of pyrrolo[2,3-d]pyrimidines at the 6-position followed by the Suzuki cross-c

A series of 7-phenylsulfanyl- or 7-(2-thienyl)sulfanyl-7-deazapurine bases bearing diverse substituents at position 6 was prepared through C–H sulfenylation of 6-chloro-7-deazapurine followed by cross-coupling or nucleophilic substitutions. The cor

A new chemoselective synthesis of pyrrolo[2,3-d]pyrimidines (7-deazapurines) bearing two different aryl groups at positions 4 and 5 was developed based on two orthogonal cross-couplings. Starting from 7-benzyl-protected 4-(phenylsulfanyl)-5-iodopyrro

Protocols for selective Pd–Cu-catalyzed direct C–H amination or C–H chloroamination of 7-deazapurines with N-chloro-N-alkyl-arylsulfonamides have been developed leading either to 8-(arylsulfonyl)methylamino-7-deazapurines or to 7-chloro-8-(aryl

6-Allylpurine derivatives are formed by Cu(I)-catalyzed coupling of (9-benzyl-9H-purin-6-yl)- magnesium chloride with allyl halides. The reaction is accompanied by allylic rearrangement in some cases. Under acid conditions the double bond of the ally
