In nature, chemical conversions take place in a confined environment and are closely
geared to each other such that the product of one reaction is the substrate or catalyst of the …

Hydrogels are polymeric networks, capable of absorbing large amounts of water and
biological fluids. They are insoluble due to the presence of chemical or physical cross-links …

The Diels–Alder (DA) reaction is a cornerstone of synthesis, yet Nature does not use
catalysts for intermolecular [4+ 2] cycloadditions. Attempts to create artificial “Diels …

The increasing need for more sustainable strategies in organic synthesis has led to a
growing interest in the use of water and other nonclassical solvents. This short review …

Selectivity rules in organic chemistry have been inferred largely from nonaqueous
environments. In contrast, enzymes operate in water, and the chemical effect of the medium …

To assess the importance of the hydrophobicity of different parts of diene and dienophile on
the aqueous acceleration of Diels− Alder reactions, second-order rate constants have been …

In orderto check whether the activated complex for the Diels-Alder reactions of 5-substituted
1, 4-naphthoquinones la-e with cyclopentadiene (2) is more polar in water than in other …

Condensation reactions between various dienes and dienophiles have been screened for
reversibility. Functionalized fulvenes, bearing in particular biological groups, and …

An efficient and convenient approach to the synthesis of 3, 3, 6, 6-tetramethyl-9-aryl-1, 8-
dioxo-octahydroxanthene derivatives using p-dodecylbenezenesulfonic acid (DBSA) as the …

A green and recoverable nano-structured diphosphate (Na2CaP2O7) was synthesized and
fully characterized using FT-IR spectra, X-ray diffraction patterns (XRD), scanning electron …
