Organocatalysis has captured the imagination of a significant group of synthetic chemists.
Much of the mechanistic understanding of these reactions has come from computational …

Macrocyclic natural products have been recognized and utilized as new platforms for
designing drugs in pharmaceutical research because the constrained three-dimensional …

In 1, 1, 1, 3, 3, 3-hexafluoro-2-propanol (HFIP) as solvent, the epoxidation of olefins by
hydrogen peroxide is accelerated up to ca. 100 000-fold (relative to that in 1, 4-dioxane as …

Chiral epoxides serve as versatile building blocks in the synthesis of complex organic
frameworks. The high strain imposed by the three‐membered ring system makes epoxides …

The design, structural characterization, and evaluation of a unique class of 1, 2, 3-
benzoxathiazine-based oxaziridines as potent O-atom transfer agents for catalytic C− H …

Four controversies on the mechanism of the olefin epoxidation with Mimoun-type
complexes,[MoO (O2) 2 (OPR3)], Herrmann-type complexes,[ReO (O2) 2Me], and related …

High level ab initio calculations have been applied to the estimation of ring strain energies
(SE) of a series of three-and six-member ring compounds. The SE of cyclohexane has been …

Herein we report the first fully quantum mechanical study of enantioselectivity for a large
data set. We show that transition state modeling at the UB3LYP-DFT/6-31G* level of theory …

The epoxidation of β-methylstyrene catalyzed by the Shi fructose-derived ketone is studied
using experimental kinetic isotope effects and DFT calculations. The observation of a large β …

We hereby report the synthesis, characterization and catalytic applications in the
epoxidation of alkenes by a vanadyl porphyrin having bulky bromo substituents at the β …
