Some transformations are not possible with ground-state reactions even in the presence of a catalyst, hence they are performed under photochemical conditions. Electron transfer occurs even with the photochemical excitement of one molecule where redox reaction is not possible at the ground state. The side products are obtained from ground-state reactions. For C-C bond formation during photochemical reaction Read More

In the last few decades, considerable research has led to the introduction of selective and efficient green as well as sustainable synthetic methods of functionalization of carbon-hydrogen bonds to form new carbon-carbon and carbon-heteroatom bonds. In this emerging field, significant development has been attained under various environmentally benign conditions including aqueous medium. In this review, we have su Read More

Five membered nitrogen heterocycles are historically known to exhibit diverse therapeutic properties. In particular, the pyrazole analogues have shown a wide range of pharmacological profiles and a number of drugs containing this scaffold approved for the treatment of various ailments and disorders. Hence, a lot of efforts have been made to develop efficient synthetic strategies for the preparation of a variety of pyrazoles in Read More

Spirooxindoles, particularly 3,3’-spirooxindoles constitute a privileged structural scaffold owing to the intensive biological activities which they possess. Because of this over the last twenty years, a large number of methods were devised for their synthesis and some of these molecules have entered pre-clinical trials. Of late, methods for spirooxindole synthesis using green protocols have developed rapidly. Reactions based on Read More

Aziridines are highly versatile intermediates in organic synthesis due to their easy access and their susceptibility to ring-opening by facile C-N bond cleavage. They are synthetically very important as they are valuable precursors of amino sugars, β-lactam antibiotics and alkaloids or present in various natural products that exhibit potent biological activities. The synthesis of this moiety from the easily available chemicals is desira Read More

Hydrolysis of Cinnamaldehyde (CNM) is one of the important processes for the production of industrially essential natural benzaldehyde. Benzaldehyde is a vital precursor in the production of perfumes, cosmetics, food, beverages, and pharmaceutical intermediates. As homogeneous base catalysts are polluting and difficult to separate, heterogeneous catalysts should be used. Hydrolysis of cinnamaldehyde to benzalde Read More
