Abstract :
Cbz-protected 2-(1-aminoalkyl)oxazole-5-carboxylates are readily obtainable by a two-step enantioselective sequence involving reaction of benzyloxycarbonyl protected amino acids with (alpha)-chloro-(beta)-ketoesters and subsequent cyclization of the resulting acyloxyketones to required oxazoles upon treatment with neat ammonium trifluoacetate.
