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.

Reductive cleavage of open chain and cyclic α-N,N-dialkylamino-substituted benzyl alkyl ethers 1a–f with a dispersion of Li metal and a catalytic amount of naphthalene in THF, allowed easy access to a wide array of α-N,N-dialkylamino-substituted benzyllithium derivatives. Reaction of these organometallics with various electrophiles afforded the expected products in satisfactory yields.
