Deuterium 155-164 synemin Homo sapiens 4-7 23487183-6 2013 The solution state structures of the 1 : 1 F(-) ion complexes containing deuterium atoms formed by a random but sequential substitution of NH protons by deuterium atoms were identified from their multiplicity patterns observed in the proton coupled (19)F NMR spectrum, which are supported by the proton decoupled (19)F NMR spectrum showing one singlet for each type of F(-) ion complex in solution for both the syn and anti isomers, correlating with their solid state structures. Deuterium 73-82 synemin Homo sapiens 411-414 17264133-7 2007 This is consistent with d(TpA)* arising by valence isomerization of a precursor cyclobutane photoproduct with cis-syn stereochemistry that is generated by [2 + 2] photoaddition of the thymine 5,6-double bond across the C6 and C5 positions of adenine.

Deuterium 91-100 synemin Homo sapiens 162-165 825244-3 1976 It is shown by deuterium substitution of the purine ring in position 8 that the orientation of the base is anti in the case of strong activators like adenosine 5"-monophosphate, and syn in that of weak activators like inosine 5"-monophosphate.

Deuterium 0-9 synemin Homo sapiens 61-64 30746080-2 2019 Deuterium-labeling experiments and control experiments were conducted to probe the mechanism, and the results indicated that the acidity of the solvent plays a critical role in the control of diastereoselectivity by trapping the adduct of nickel hydride to C[double bond, length as m-dash]C bonds via protonolysis, giving the hydrogenation product with stereospecific syn-selectivity.

Deuterium 0-9 synemin Homo sapiens 41-44 26968748-4 2016 Deuterium-labelling studies indicate the reactions proceed through syn-aminopalladation of the alkene and suggest that the control of syn- versus anti-aminopalladation pathways is important for asymmetric induction.
