Synthesis of modified uracil and cytosine nucleobases using a microwave-assisted method

Modified nucleobases and nucleic acids have found many biological and pharmaceutical applications. Here we report a microwave-directed synthesis of a variety of modified uracil and cytosine nucleobases with high yields under solvent-free conditions. The reaction yields were further improved by addition of Lewis acid. The crystal structures of 5-isopropyl-6-methyluracil and 6-phenyluracil were also determined.

Solid-phase synthesis (SPS) of substituted uracils via Oxone cleavage methodology

An original and highly efficient Oxone cleavage methodology for the solid-phase synthesis of substituted uracils has been developed. An example of application of this methodology to the solid-phase synthesis of uridine derivatives is also reported.

New procedures for the synthesis of heterocyclic substituted and 2,4-difunctionalized pyrimidines

N-Tosyl-2-and -3-acetylpyrrols 1 or N-tosyl-2-pyrrolidone 5 were condensed with cyano compounds in the presence of triflic anhydride (Tf2O) to yield heteroarylpyrimidines. 2,4-Difunctionalized pyrimidines were obtained by reaction of the corresponding 2,4-bis(methylsulfonyl)pyrimidines with nucleophiles.

A useful methodology for the regioselective deprotection of 1,3-dibenzyluracils

A practical, regioselective N-1 deprotection of 1,3-dibenzyl uracils 2 a-e is described. The same experimental procedure and longer reaction time afforded the complete deprotection of the uracils.
