The specific rotation of L-dopa in water (at 15C) is -39.S. A chemist prepared a mixture of L-dopa and its enantiomer, and this mixture had a specific rotation of 31. Calculate the % ee of this mixture. \%ee - 56 The specific rotation of ephedrine in ethanol (at+20C) is 6.3. A chemist prepared a mixture of ephedrine and its enantiomer, and this mixture had a specific rotation of 2.2. Calculate the % ee of this mixture. \%ee - The specific rotation of vitamin B7 in water (at2C) is +92. A chemist prepared a mixture of vitamin B7 and its enantiomer, and this mixture had a specific rotation of +74. Calculate the :. ee of this mixture. Wi ee= Synthetic chemists often employ enzymes to conduct asymmetric syntheses that favor the production of one enantiomer over another. Baker's yeast was used to convert the diketone shown into alcohol 1, with an ee of 84%. (Tetrahedron Asymmetry 2014,25 . 340-347.) The specific rotation for the pure (S) enantiomer of 1 is reported to be +88.6. Calculate the expected specific rotation for the sample of 1 that was synthesized with baker's yeast.
