Abstract:
Palladium-catalyzed intramolecular direct C–H arylations for the synthesis of hitherto unknown fused hetero systems containing an incorporated pyrrolo[2,3-d]pyrimidine scaffold are described. Pyrimido[5′,4′:4,5]pyrrolo[2,1-a]isoindoles were synthesized from 2,4-di­arylpyrrolo[2,3-d]pyrimidines and o-bromobenzyl bromides by using a cascade N-benzylation/C–H arylation reaction sequence. A series of pyrimido[5′,4′:4,5]pyrrolo[1,2-f]phenanthridines were successfully assembled via a domino process involving the palladium-catalyzed direct double C–H arylation reactions of 2,4,7-triarylpyrrolo[2,3-d]

Discovery of compound 1 as a Zika virus (ZIKV) inhibitor has prompted us to investigate its 7H-pyrrolo[2,3-d]pyrimidine scaffold, revealing structural features that elicit antiviral activity. Furthermore, we have demonstrated that 9H-purine or 1H-pyrazolo[3,4-d]pyrimidine can serve as an alternative core structure. Overall, we have identified 4,7-disubstituted 7H-pyrrolo[2,3-d]pyrimidines and their analogs including compounds 1, 8 and 11 as promising antiviral agents against flaviviruses ZIKV and dengue virus (DENV).

ABSTRACT We have previously shown that a series of nonnucleoside pyrrolo[2,3-d]pyrimidines selectively inhibit the replication of herpes simplex virus type 1 (HSV-1) and human cytomegalovirus (HCMV). These compounds act at the immediate-early or early stage of HCMV replication and have antiviral properties somewhat similar to those of roscovitine and olomoucine, specific inhibitors of cyclin-dependent kinases (cdks). In the present study we examine the hypothesis that pyrrolo[2,3-d]pyrimidines exert their antiviral effects by inhibition of cellular cdks. Much higher concentrations of a panel o

A simple and efficient one-pot procedure for the synthesis of new pyrrolo[2,3-d]pyrimidine derivatives has been established through an l-proline-catalyzed cyclization of 6-aminopyrimidine-4(3H)-one with nitroolefins in water. The reaction at 80 °C in water gives various highly substituted pyrrolo[2,3-d]pyrimidines in good to excellent yields. This procedure has the advantages of environmental friendliness, good yields, and convenient operation.

ABSTRACT Rhesus and human cytomegalovirus (RhCMV and HCMV, respectively) exhibit comparable inhibition by benzimidazole nucleosides, including 2,5,6-trichloro-(1-β-d-ribofuranosyl)benzimidazole (TCRB), and pyrrolo[2,3-d]pyrimidines. The two HCMV protein targets of TCRB, UL89 and UL56, are highly conserved with their RhCMV homologues. These data indicate that infection of rhesus macaques with RhCMV represents a useful model to test novel anti-HCMV drugs.

Abstract:
This report highlights the recent advances in direct C–H bond functionalization of 5,5- and 6,5-fused heterocycles containing at least two nitrogen atoms. Besides C–C bond formation, C–N, C–S, C–P, and C–Si bonds can also be created via a metal-catalyzed process. Some examples, where a C–H functionalization approach was applied for the synthesis of drug candidates, will be presented as well.1 Introduction2 C–H Functionalization Reactions of N-Containing Heterocycles2.1 Imidazo[1,2-a]pyridines2.2 Pyrrolo[1,2-a]pyrazines2.3 Imidazo[1,2-b]pyrazoles2.4 Imidazo[1,2-a]pyrimidines2.5 Imidazo[1,2-a]py
