The efficient and sustainable development of deep marine carbonate rock reservoirs in the
Sichuan Basin has higher technical requirements for reservoir acidizing alteration …

Reactant solubility, which dictates achievable concentrations, and the stability of reaction
intermediates (excited states), solvents modulate the potential energy landscape and …

First, the nucleophilic substitution reactions of pentafluoropyridine (PFP) with
hydroxybenzaldehydes were evaluated. It was demonstrated that parameters such as …

In this study, a series of novel pyrazole-based compounds were synthesized starting from
the precursor ethyl 3-(4-amino-1-phenyl-3-((4-sulfamoylphenyl) carbamoyl)-1 H pyrazol-5 …

In a one-pot synthesis, all the reactants undergo consecutive chemical reactions in a single
pot. Because the tedious separation and purification of the intermediate chemical …

Background: A number of research were conducted on the pyran and thiophene derivatives,
which were attributed to have a wide range of biological activities, including anti-plasmodial …

In this review we consider the possibilities for using metal oxides as heterogeneous
catalysts of multicomponent reactions, leading to pharmacologically relevant heterocyclic …

There are a lot of lucrative plant species found in the Amazon and camu-camu (Myrciaria
