Investigation on possibility of rearrangement of pyrimidine-5-carboxylic acids esters
Scherbinina,Dar'In,Lobanov
experimental part, p. 1109 - 1115 (2011/10/02)
A previously reported rearrangement of pyrimidine-5-carboxylic acids esters to 5-acylpyrimidones does not, in fact, occur in any of the examples studied by us.

HIV integrase is essential for HIV replication. However, there are currently no integrase inhibitors in clinical use for AIDS. We have discovered a conceptually new β-diketo acid that is a powerful inhibitor of both the 3′-processing and strand transfer s
Isomerization/recyclization of some 5-ethoxycarbonyl-pyrimidines

This communication reports on the investigation of a new recyclization conversion of a pyrimidine ring, which can be referred to as C-C recyclization. In this reaction the nucleophile cleaves the pyrimidine ring at the N(3)-C(4) bond, and following rotation around the single C(5)-C(6) bond the new cyclization takes place. This type of recyclization has general applicability, and takes place upon alkali treatment of substituted 4-methyl-5-ethoxycarbonyl- and 4-amino-5-ethoxycarbonyl-pyrimidines (1) which are transformed respectively to 4-hydroxy-5-acetyl- and 4-hydroxy-5-carbamoylpyrimidines (2). The obtained pyrimidyl-ketones can be readily converted to their hydrazones 7-12.

The preparation of E and Z isomers of 3-ureido-2-cyano-2-propenoates Ia-Id and their base-catalyzed isomerization and cyclization to 5-carboxycytosine derivatives IIa-IIf and 5-cyanouracil derivatives IIIa and IIIb is described.Also described is the preparation of 3-ureido-2-acyl-2-propenoates Va-Vd and their base-catalyzed cyclization to 5-carboxy-2(1H)-pyrimidone derivatives VIa-VIc and 5-acyluracils VIIa-VIIc.
