As part of our ongoing studies on the synthesis (R)-modafinil and its derivatives, we previously described both resolution(3) and enantioselective methods.(4) (R)-Modafinil can be obtained by resolution using either chiral chromatography or preferential crystallization of its precursor, (RS)-modafinic acid.(3, 5) However, such nondynamic resolution procedures suffer from a major drawback with respect to enantioselective syntheses, ie the inherent ...
