"Chemical Equation Presented" The combination of catalytic amounts of [(R)-DTBM-SEGPHOS]CUH In the presence of stoichiometric DEMS (dlethoxymethylsllane) In toluene at room temperature leads to asymmetric reductions of 4-substituted coumarins. Several targets or their known precursors can be prepared In high yields and ee's, Including the muscarine receptor antagonist (R)-tolterodine.
