This review summarizes the data on the stereochemical structure of functionalized azoles
(pyrazoles, imidazoles, triazoles, thiazoles, and benzazoles) and related compounds …

In the current study, new morpholine-linked thiazoles were prepared by the reaction of
salicylaldehyde derivative, thiosemicarbazide, and α-bromoketones. To mediate the …

We report herein the utility of the morpholine-linked benzaldehyde as a key building block in
the preparation of two series of new chromene-thiazoles with potential bioactivities. In this …

A three-component protocol involving the reaction of 3-aminothieno [2, 3-b] pyridine-2-
carboxylate, Me 2 NCH (OMe) 2 and heteroaryl (bis) amines in dioxane under microwave …

A simple, efficient and highly regioselective method for the preparation of 3, 4-and 4, 5-
disubstituted N-methylpyrazoles in a one-pot procedure is reported. The methodology …

In this study, the synthons 2-hydroxy-5-((arylthio) methyl) benzaldehydes were reacted with
1, ω-dihaloalkanes to produce the corresponding bis (aldehydes). The previous precursors …

An efficient and controlled site-selective annulation of 3, 5-diethoxycarbonyl 4-hydrazonyl
pyrazoles is described. The relative proportion of the products is affected by hydrazone …

Heterocyclic compounds are of very much concern in our daily life. These 
compounds constitute the largest and most varied family of organic compounds …

Abstract The condensation of 4, 4-dichlorobut-3-en-2-one with aromatic aldehydes in the
presence of a catalytic amount of sulfuric acid afforded 1, 1-dichloro-5-(4-R-phenyl) penta-1 …

Pyrazoles have potential applications in the agrochemical and medicinal chemistry
industries as pesticides, anti-inflammatory medications, and antitumor drugs. Fluorinated …
