Reductive cleavage of N-substituted 2-aryl-1,3-oxazolidines: generation of .alpha.-amino-substituted carbanions
摘要:
The behavior of several N-substituted 2-aryl-1,3-oxazolidines has been investigated under conditions of electron transfer from alkali metals in aprotic solvents. The reduction led to the regioselective cleavage of the benzylic carbon-oxygen bond, with formation of the corresponding N-substituted benzylamino alcohols in good yields. Investigation of the mechanism of this reductive cleavage, with the aid of labeling experiments, showed the intermediate formation of alpha-tertiary amino-substituted carbanions.
