The activation and transformation of organic chemical bonds is a fundamental scientific
problem. In the past several decades, C–S bond cleavage for the construction of C–C and C …

Dimethyl sulfoxide (DMSO) has had a long history of use as a polar solvent and active
pharmaceutical ingredient in the past decades. However, in this decade DMSO has attracted …

A cascade reaction between enaminones, hydrazines, and dimethyl sulfoxide (DMSO) for
the synthesis of 1, 4-disubstituted pyrazoles catalyzed by molecular iodine in the presence …

The recent advances in the syntheses of various heterocycles based on pyridinium ylides
are described. Depending on the reactivity of the pyridinium ylides and the reactants, a …

Dimethyl sulfoxide (DMSO), as extremely important aprotic polar solvent and reaction
medium, has attracted widespread attention from chemists in recent years due to its wide …

The synthesis of N-heterocycles composes a significant part of synthetic chemistry. In this
report, a Cu (II)-catalyzed green and efficient synthesis of pyrrolo [1, 2-a] quinoxaline …

Transition metal-free organic transformations using K2S2O8 is one of the most efficient
methods for the formation of carbon–carbon/carbon–heteroatom bond in organic synthesis …
