salt of 2,6‐difluorophenylacetonitrile followed by treatment with aqueous sodium hydroxide in methanol, alkylation, reduction, halogenation, and/or acidic hydrolysis. All synthesized compounds were evaluated for their activity against HIV‐1. The most active compound in this study was compound 7, which showed activity against HIV‐1 comparable to that of MC‐1220. The only difference in structure between

A facile and novelsyntheticroute to MC-1220 was achieved by condensation of 4,6-dichloro-N,N-5-trimethylpyrimidin-2-amine (1) with the sodium salt of 2,6-difluorophenylacetonitrile, followed by methylation and strong acidic hydrolysis. The prodrugs of MC-1220 were synthesized by reaction of chlorophosphoramidate derivatives (7a–e) or α-acetobromoglucose with the sodium salt of MC-1220. The stability

1,5-Disubstitutedpyrimidine-2,4-diones were synthesized by fusion of 5-bromouracil with an aniline derivative followed by coupling with benzyl halide whereas the opposite synthesis sequence failed. Also 4,6-dichloro-N,N,5-trimethylpyrimidin-2-amine was treated with phenols. The products were tested for their activity against HIV-1.

Easy street: Herein we describe a novel and practical synthesis of the anti‐HIV compound MC‐1220. Through the use of inexpensive reagents and commercially available starting materials, MC‐1220 and itsanalogues are more easily accessed by a four‐step procedure involving a key reduction step.

anti‐HIV‐1 activity, the possibility for asymmetric synthesis of its potential precursors is explored. Here, we investigateasymmetricreduction of the vinyl double bond of 6‐(1‐arylvinyl)pyrimidine derivatives to their corresponding ethylidene analogues. Catalysts with ligands bearing trivalent phosphorus ligating the soft metals rhodium(I), ruthenium(II), or iridium(I) are used for asymmetric reduction
