Simple three-component reactions between dialkyl acetylenedicarboxylate, primary amines and isothiocyanates in the presence of catalytic amount of ZnO nanorods are investigated in water at room temperature which produced thiazole derivatives in good yields.

A novel, convenient and efficient three-component reaction for synthesizing substituted pyrroles from primary amines and electron deficient acetylenic compounds in the presence of ammonium thiocyanate in water leads to the formation of pyrroles in good yields.

In this research, we established a modified 45 flammability test for cotton blend material to measure the flammability of nanosilicone softener treated-cotton blend material. The wet pick-up was about 150±10%. b) The specimens were tested in the cross direction and nine specimens were measured. The average percent weight loss of the untreated cotton blend nonwoven is only 0.9%. The percent weig...

OBJECTIVE The present study was carried out to evaluate the toxic effect of blend of some food colors on Swiss albino rats. MATERIALS AND METHODS A blend (1:1:1) of sunset yellow, metanil yellow and tartrazine showed additive effects on serological parameters which indicate that addition of these dye together in food stuff may give rise to more toxic effects than are produced by each dye indi...

In this paper we propose an analysis of the metaphor "This surgeon is a butcher!” discussed in Grady, Oakley & Coulson 1999, introducing it into a mental space framework derived from blending theory and cognitive semiotics. We attempt to reconstruct the meaning of this metaphor, and hypothesize a general framework for analyzing metaphoric blends and other forms of expression that utilize blends...

C,N-coupling reactions of aryl chlorides and aryl amines catalyzed by a nickel catalyst are reported. 17 new amines are synthesized in yields of 57-99%. 2,6-Dichloro substituted imines can be selectively aminated. Both mono- and di-aminated products are obtained. Different substrates and amines are tested to look into the influence of electronic effects and steric hindrance to the reaction. An ...

Tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and N-Boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (MTSA). All reactions were performed at room temperature in good to high yields.

The rhodium-catalyzed regioselective amination of tertiary allylic trichloroacetimidates with unactivated aromatic amines is a direct and efficient approach to the preparation of α,α-disubstituted allylic aryl amines in good yield and with excellent regioselectivity. This method is applicable to a variety of unactivated primary and secondary amines and allows for the preparation of reverse pren...

109 Biogenic amines are a group of organic nitrogenous compounds formed and degraded by the metabolisms of living organisms (microorganisms, plants and animals). The main biogenic amines associated with wine are putrescine, histamine, tyramine and cadaverine, followed by phenylethylamine, spermidine, spermine, agmatine and tryptamine. Biogenic amines in wine can be formed by various microorgani...

Four Holstein steers (466 kg) with cannulas in the rumen and proximal duodenum were used in a 4 X 4 Latin square design experiment to evaluate the ruminal escape protein value and post ruminal digestibility of menhaden fish meal (FM) vs two high-bypass protein blends in an 88% concentrate finishing diet. Blend 1 (B-1) contained 5% fish meal, 25% meat and bone meal, 20% blood meal, and 50% hydro...
