The fields of theoretical and computational chemistry have come a long way since their
inception in the mid-20th century. Fifty years ago, only rudimentary approximations for very …

Levoglucosenone (LGO) is a valuable anhydrosugar product from fast pyrolysis of
cellulose/biomass, but its formation mechanism is still unclear at present. In this study …

Considering the unique electronic properties of the CF2 and the CN groups, the CF2CN
group has significant potential in drug and agrochemical development, as well as material …

Aplydactone is an unusual brominated sesquiterpenoid isolated from the sea hare Aplysia
dactylomela. Its highly strained skeleton contains two four‐and three six‐membered rings …

Reductive desulfurisation of dithiocarbamates is conveniently achieved using H3PO2–Et3N–
ACCN in refluxing dioxane. Fused and spirocyclic β-lactams, prepared through 4-exo trig …

Kinetics of ring opening of the 1-cyclobutyldodecyl radical (1) were studied, and an
Arrhenius function over the temperature range− 20 to 47° C was determined. The radical …

The photochemical [2+ 2] cycloaddition of (S)-4-methyl-5-O-pivaloyloxymethyl-2 (5 H)-
furanone, 5, to vinyl acetate, vinyl pivalate, tert-butyl vinyl ether, 1, 1-diethoxyethylene, and …

Crich ligation is a new method for the functionalization of peptides and proteins under mild
conditions. To more fully understand the mechanism of the ligation and to explore the effect …

Abstract Cyclobutanes derived from [2+ 2] photocycloaddition reactions of tetronic acid
esters were subjected to free-radical fragmentation reactions. The product formation was …

DFT (U) B3LYP/6-31G (d, p),(U) B3LYP/6-31+ G (d, p), and (U) B3LYP/6-311+ G (d, p)
calculations were carried out to investigate the ring opening reactions of the …
