2,2-Disubstituted 2,5-dihydro-4-methyloxazoles (1) were synthesized from 2-aminopropanol in three steps. 3-Oxazolines 1 can be converted into various α-sulfinyl ketimines such as (SS)-(4-methylphenyl)sulfinylmethyl}-2,2-diethyl-2,5-dihydrooxazole (5) which was stereoselectively reduced with Dibal-H to give 3-hydroxy-2-aminopropyl sulfoxide 7.
