A route to the alkylation of the carbon α to the nitrogen of secondaryamines 1a,c–g is proposed which is based upon a new and efficient synthesis of oxazolidines 3 from β- hydroxy tertiary amine N-oxides 2.

N-Hpyrrolidines are obtained from intermolecular 3+2cycloaddition reactions between nonactivated olefins and ylide generated from amine N-oxide structurally designed in such a way as to allow easy dealkylation of the cycloadduct.
