Efficient preparation of N-phenylsulfenyl ketimines from oximes or nitro compounds without racemization of alpha-stereocenters.
As N-sulfenyl imines (e.g., RR'C=N-SAr) can be readily transformed to their N-sulfinyl imines (RR'C=N-SOAr), N-sulfonyl imines (RR'C=N-SO2Ar), and N-sulfonyl oxaziridines, the very mild procedure developed to convert ketoximes and secondary nitro derivatives to N-arenesulfenyl ketimines constitutes a new and efficient route to all these series of compounds. The configuration of the alpha-stereo...
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
Uptake of metal cations by fibroblasts ilz nitro
Atomic absorption spectroscopy was used to assess uptake of Ag+l, A u + ~ , Cd+2, CU’~, In+3, Ni+2, Pd+’, and Zn+’ by in vitro cultures of Balb/c 3T3 fibroblasts as a function of concentration of the cations in cell-culture medium. Reversibility of this uptake was also measured. Metal cations exhibited a 400-fold difference in their tendency to accumulate in the cells; In+3 tended to accumulate...
متن کاملDirectionality of π-holes in nitro compounds.
A statistical survey of the Cambridge Structural Database reveals that the interaction between the π-holes of nitro groups and electron-rich atoms is somewhat directional. High-level ab initio computations indicate energies up to -6.6 kcal mol(-1).
متن کاملA novel strategy for the preparation of arylhydroxylamines: chemoselective reduction of aromatic nitro compounds using bakers' yeast.
Using bakers' yeast as a biocatalyst, the chemoselective reduction of aromatic nitro compounds bearing electron-withdrawing groups gave the corresponding hydroxylamines with good to excellent conversion under mild conditions.
