We report herein the first synthesis of biologically active natural bromophenols, namely 1-(2,3,6-tribromo-4,5-dihydroxybenzyl)pyrrolidin-2-one (2), 2RS-1- (2 ,3-dibromo-4 ,5-dihydroxybenz yl)-5-oxopyrrolidine-2-carboxylic ...

Some novel derivatives of thiosemicarbazide and 1,2,4-triazole-3-thiol were synthesized and evaluated for their biological activities. The title compounds were prepared starting from readily available pyridine-2,5-dicarboxylic ...

A series of tetrahydropyrimidinethiones were synthesized from thiourea, -diketones and aromatic aldehydes, such as p-tolualdehyde, p-anisaldehyde, o-tolualdehyde, salicylaldehyde and benzaldehyde. These cyclic thioureas ...

In the presence of trifluoroacetic acid, on the basis of three-component condensation of phenylthiourea with its salicylaldehyde and methyl-3-oxobutanoate, an efficient method for the synthesis of 1-(4-(2-hydroxyphenyl)- ...

In this study, a series of novel bromophenols were synthesized from benzoic acids and methoxylated bromophenols. The synthesized compounds were evaluated by using different bioanalytical antioxidant assays including ...

The Achillea genus belongs to the Asteraceae family, which is mostly found in the northern hemisphere and is comprised of 115 species in the world. In Turkish flora, there are 52 species and 58 taxa, among them half of ...

In this study, phytochemical components and antioxidant capacity of extracts obtained from Iris taochia plant, which is endemic to Caucasus, were investigated. Fifteen new compounds were detected and identified using a ...

Olivetol is a pioneer in diverse syntheses of tetrahydrocannabinol. It is produced by a type of insects, which is used as a pheromone, antiseptic, or repellent agent. In this study, we evaluated the antioxidant properties ...

In this study, series of novel bromophenol derivatives were synthesized and investigated for their antioxidant and AChE inhibition properties. Novel brominated diarylmethanones were obtained from the acylation reactions ...
