Chromones, six-membered oxygen heterocycles, and pyrazoles, five-membered two-adjacent-nitrogen-containing heterocycles, represent two important classes of biologically active compounds. Certain derivatives of these scaffolds play an important role in medicinal chemistry and have been extensively used as versatile building blocks in organic synthesis. In this context, we will discuss the most r...

Molecular sieves MCM-41 were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO2: 1.6EA: 0.215HDTMABr: 325H2O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing 5.0 and 10.0 wt.% of Cu was synthesized unde...

Recently, solid-phase synthesis has been recognized as an important methodology for combinatorial chemistry or automated synthesis directed at drug discovery. Various synthetic methodologies have been applied to solid-phase synthesis, although it appears that organometallic chemistry in this area is still being explored. In solution-phase chemistry, organometallic reagents have been utilized fo...

Organic carbamates represent an important class of compounds showing various interesting properties. They find wide utility in various areas as pharmaceuticals, agrochemicals (pesticides, herbicides, insecticides, fungicides etc.), intermediates in organic synthesis, protection of amino group in peptide chemistry, and as linker in combinatorial chemistry etc. Classical synthesis of carbamates i...

2-Pyridones are important heterocyclic compounds that are widely used in medical chemistry, and their various derivatives have significant biological and medical applications. In this paper, the synthesis of 2-pyridones as well as 2-pyridone-based compounds, such as 2-quinolones, using microwave assisted organic chemistry is reviewed. The review is divided in three parts. In the first part, mic...

A few months before the COVID-19 pandemic, Pierre Vogel and Kendall N. Houk published with a new textbook Wiley-VCH, “Organic Chemistry: Theory, Reactivity, Mechanisms in Modern Synthesis”, foreword from late Roberts H. Grubbs. The book demonstrates how catalytic processes dominate all fields of modern organic chemistry synthesis, invention combines thermodynamics, kinetics, spectroscopy, quant...
