Since it is recognized that carbohydrates, as free oligosaccharides and constituents of glycoconjugates, play important roles in many biological functions of glycoproteins, a variety of analytical techniques have been developed for highly sensitive detection and analysis of complex oligosaccharides obtained from a variety of biological media [1]. Presently, among many analytical techniques, mas...

1-alkyl aryl-5-amino-4-(cyanoformimidoyl)imidazoles 4 were reacted with malononitrile and 2-amino-1,1,3-propenetricarbonitrile under mild experimental conditions, which led to 5-amino-3-(substituted benzyl)-6,7-dicyano-3H-imidazo[4,5-b]pyridines 5 and 6,8-diamino-3-(4-substituted benzyl)-3H-imidazo[4,5-b]-1,8-naphthyridine-7,9-dicarbonitrile 6, respectively, when the reaction was carried out in...

A case is reported of deliberate release of CS gas (O-chlorobenzylidene malononitrile) in an enclosed space and the consequences for an accident and emergency department.

The reactivity of the product believed to be 2-(1-phenyl-2-thiocyanato-ethylidene)malononitrile toward a variety of electrophilic and nucleophilic reagents is reported.

An organocatalytic three-component reaction of isatins, malononitrile and isocyanoacetates provided 3,3'-dihydropyrryl-spirooxindoles in excellent yields and enantioselectivities. The products could be readily converted to valuable 3,3'-pyrrolidinyl-spirooxindoles.

<p>In this research, we have described a facile and user-friendly protocol for the formation of 2((1H-Indole-3yl)(Phenyl)methyl)malononitrile derivatives using recoverable efficient TiO2 nanocatalyst. This is simple incredibly synthesis novel derivatives. Nanoscale used as catalyst. Since TiO<sub>2 </sub>has more surface area easily binds with active site reactive molecule ini...

1) As part of the Tropical Rivers Inventory and Assessment Project (TRIAP), a databaseof 94,148 waterbird records was assembled, comprising 82,596 records from the TRIAParea and 11,552 records from a surrounding 10 km buffer. These records were sourcedfrom databases for Atlas1 and Atlas2 provided by Birds Australia, 99.1% of which arefrom the Historical Atlas (pre-1977), the...
