An efficient and simple KOtBu promoted selective ring-opening N-alkylation of 2-methyl-2-oxazoline or 2-(methylthio)-4,5-dihydrothiazole with benzyl halides under basic conditions has been described for the first time, which provides a convenient and practical pathway for the synthesis of versatile 2-aminoethyl acetates and N-Substituted thiazolidinones with good functional group tolerance and selectivity. KOtBu not only plays an important role to promote this ring-opening N-alkylation, but also acts as an oxygen donor.
