The reduction of a number of N-substituted succinimides with lithium aluminum hydride has been studied. In all but one case reduction to the N-substituted pyrrolidines occurs smoothly. N-Benzhydryl, Nt-butyl and N-phenylsuccinimides undergo ring opening to yield the respective amino alcohols in addition to the normal reduction product. N-Tritylsuccinimide gives only N-trityl-4hydroxybutyramide. Several succininamic acids have been reduced to ...
