Abstract:

A novel photochromic diarylethene bearing a pyrimidine moiety, 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2-methyl-5-(3-cyano)-3-thieny-l] perfluorocyclopentene has been synthesized. Its properties, including photochromic behavior and fluorescent properties, have been investigated. The compound exhibited remarkable photochromism, changing from colorless to blue after irradiation with UV light. The results indicated that the pyrimidine moiety played a very important role during the process of photoisomerization reactions.

Abstract:

Some pyrimidin-2- and pyrimidin-4-amines were treated with isocyanates and isothiocyanates to give the corresponding disubstituted ureas or thioureas . A pyrimidin-2-amine is more reactive than a pyrimidin-4- amine in these reactions. 2-Aminothiazoles and thiazolinones also react to give the disubstituted ureas or thioureas . The use of ethoxycarbonyl or benzoyl isothiocyanate or isocyanate gives products which are readily hydrolysed to the pyrimidinyl or thiazolyureas or thioureas but with concomitant hydrolysis and decarboxylation of an ethoxycarbonyl substituent .

Novel thiazolidine-2,4-dione (TZD) based pyrimidine derivatives have been synthesized by Knoevenagel condensation reaction between thiazolidine-2,4-dione and amino pyrimidinyl aliphatic aldehydes followed by heterogeneous metal reduction. Synthetic strategy involved nucleophillic substitution of hydroxyl protected six membered aliphatic chain on 4,6-dichloropyrimidine followed by Suzuki coupling. This approach is regioselective, efficient and versatile for synthesis of such analogs

Abstract:

Background: With few exceptions, existing tuberculosis drugs were developed many years ago and resistance profiles have emerged. This has created a need for new drugs with discrete modes of action. There is evidence that tuberculosis (like other bacteria) is susceptible to oxidative pressure and this has yet to be properly utilised as a therapeutic approach in a manner similar to that which has proven highly successful in malaria therapy. Objective: To develop an alternative approach to the incorporation of bacterial siderophores that results in the creation of antitubercular peroxidic leads f

Abstract:

The potential of pyrimidines to serve as ditopic halogen-bond acceptors is explored. The halogen-bonded cocrystals formed from solutions of either 5,5′-bipyrimidine (C8H6N4) or 1,2-bis(pyrimidin-5-yl)ethyne (C10H6N4) and 2 molar equivalents of 1,3-diiodotetrafluorobenzene (C6F4I2) have a 1:1 composition. Each pyrimidine moiety acts as a single halogen-bond acceptor and the bipyrimidines act as ditopic halogen-bond acceptors. In contrast, the activated pyrimidines 2- and 5-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine (C14H13N3) are ditopic halogen-bond acceptors, and 1:1 halogen-bonded cocrysta

Abstract Reaction of 4-amino-N-(4,6-dimethyl-2-pyrimidinyl)benzenesulfonamide (sulfamethazine) with diazomethane yields not only 4-amino- N-(4,6-dimethyl-2-pyrimidinyl)-iV-methylbenzenesulfonamide but also 2-(4-aminobenzenesulfonimido)-1,4,6-trimethyl-1,2-dihydropyrimidine. Yields of the latter compound are highly variable and the compound does not show a response to gas chromatography. Thus, results of gas chromatographic determinations of residues of some sulfa drugs in edible meat tissues may be erroneous when diazomethane derivatization is used.

A rhodium-catalyzed intermolecular highly stereoselective 1,3-dienylation at the 2-position of indoles with non-terminal allenyl carbonates has been developed by using 2-pyrimidinyl or pyridinyl as the directing group.

Abstract:

Continuing our research in the field of new heterocyclic compounds, herein we report on the synthesis and antitumor activity of new amino derivatives of pyrido[3’,2’:4,5](furo)thieno[3,2-d]pyrimidines as well as of two new heterocyclic systems: furo[2–e]imidazo[1,2-c]pyrimidine and furo[2,3-e]pyrimido[1,2-c]pyrimidine. Thus, by refluxing the 8-chloro derivatives of pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidines with various amines, the relevant pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidin-8-amines were obtained. Further, the cyclization of some amines under the action of phosphorus oxychlori

Abstract:

The pyrimidinyl-directed C–H functionalization of indolines with anthranils as amination sources under rhodium(iii) catalysis is described to afford a range of C7-aminated indoline derivatives with excellent site-selectivity and functional group compatibility.
