n structure I was converted to quinine (A), other compounds were formed, including compound D. Horo a) There are carbon stereocenters in structure D. Assign the R and S configuration at each stereocenter of D. b) The quinine isolated from this reaction was found to have a specific rotation of [a] =+35° (c = 1, CHC13). Following a chiral resolution the specific rotation was found to be [«]17 = -108° (c = 1, CHCl). The specific rotation of the desired...
