Mini-Reviews in Organic Chemistry - Volume 15, Issue 3, 2018

A survey of literature covering the synthesis of xanthene dyes and their applications during the period 2000-2016 is carried out. A comparison of various synthetic strategies in terms of major starting materials and catalysts used has also been presented. Furthermore, a discussion of pH and metal cations detection has been provided for some well known xanthene chromophores and their derivatives. This review aims to exa Read More

Background: Propargyl compounds such as propargyl alcohols and propargyl amines having several reactive centers have attracted a lot of attention for their various transformation. In particular, these compounds have been recently used as the versatile synthons in the synthesis of various heterocycles via their intramolecular cycloisomerization or cyclocondensation with other unsaturated compounds under differen Read More

Current research follows the postulates of green chemistry specifically in the field of chemistry like implementation of solvent free systems, use alternatives to conventional organic solvents, recovery of catalysts, etc. Chiral ionic liquids are those compounds which fulfil the conditions of green chemistry due to their unique properties. Their syntheses from natural resources like carbohydrates make them more valuable and enro Read More

Background: Quinoxaline-based derivatives present a group of very important heterocyclic pharmacophores which occupied the attention of a large number of scientists in the last few decades. Compounds with quinoxaline fragment have significant antitumor and antiviral potential, proved by an in vitro or/and in vivo study, and possess therapeutic potential. Conclusion: In this review article, we present an overview of the de Read More

Natural polymer flocculants (NPF) and their derivatives as the eco-friendly, nontoxic and biodegradable materials have attracted significant attention in water treatment. The graft polymerization of NPF and its synthesis mechanisms that have been proposed in the literature are mainly reviewed in this paper. Initiation system is the key factor in the modification of NPF and it influences the characteristics of copolymer in t Read More

Chiral ionic liquids with a focus on their applications in asymmetric Michael additions and related reactions were reviewed. The examples were classified on the basis of the mode of asymmetric induction (e.g., external induction/non-covalent interaction or internal induction/covalent bond formation), the roles in reactions (as a solvent or catalyst), and their structural features (e.g., imidazolium-based chiral cations, other chi Read More
