Enantiomerically enriched cyanohydrin O-phosphates, prepared
by enantioselective cyanophosphorylation of α,β-unsaturated
aldehydes, react regioselectively at the γ-position
with organocuprates derived from alkyl Grignard reagents
and CuCN to afford chiral γ-alkyl-substituted α,β-unsaturated
nitriles. The configuration of the new C–C double bond

The analytical approximate technique developed by Wu et al. for conservative oscillators with odd nonlinearity is used to construct approximate frequency-amplitude relations and periodic solutions to the relativistic oscillator. By combining Newton's method with the method of harmonic balance, analytical…

Although dynamic and stretching exercises have been widely investigated, there is little information about warm up performed by tag games. Thus, the purpose of the present study was to verify the acute effect of dynamic exercises compared to a tag…
