A combination of Novozym 435-catalyzed methanolysis and amidation using racemic N-methyl-5-acetoxytridecan- and tetradecanamides as a substrate proceeded in good enantioselectivity to afford the corresponding (R)-N-methyl-5-acetoxyalkanamides, (S)-N-methyl-5-hydroxyalkanamides, and (S)-N-cyclohexyl-5-hydroxyalkanamides. Both enantiomers of δ-tri- and δ-tetradecalactones were synthesized in over...

Highly enantioselective palladium-catalyzed formal hydrogenolysis of racemic N-sulfonyloxaziridines has been realized, providing a novel access to sultams with up to 99% ee. Preliminary mechanistic insights revealed that the reaction proceeded through a N-O bond cleavage, dehydration, and the sequential asymmetric hydrogenation.

The cyclic hydroboration of 2,7-dimethyl-2,6-octadiene (6) was studied. It was found that the stereochemical outcome of the reaction was dependent upon the solvent, temperature, time and the nature of the borane reagent. Pure racemic trans-2,5diisopropylborolane (14) was isolated following selective complexation of the cis-2,5diisopropylborolane (15) with 1-(2-hydroxyethyl)-pyrrolidine.

in order to study of ecological and phenological traits of ferulago angulata asan important medicinal plant, this research was conducted in hezar mountains andbondareh henza in kerman province, iran. random samples of this plant were taken andtheir vegetation habitat conditions and their growth characteristics including height ofcollar leaves, height of flower stem, flower stem number and forag...

For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree Diameter at Breath Height in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran ...

In this study, curvilinear regression was applied to the relationship between BMI and body fat percentage, and an analysis was done to see whether there are characteristic changes in that curvilinear regression from elementary to middle school. Then, by simultaneously investigating the changes with age in BMI and body fat percentage, the essential differences in BMI and body fat percentage were...
