Abstract:L-Phenyl-alamine was Boc-protected to afford N-Boc-L-phenyl-alamine after using an one-pot method including acylating chlorination, substitution, decarboxylation and chlorination. (S)-4-Phenyl-3-(N-Boc-amino)-1-chloro-2-butanone (6) was obtained with a yield of 70.4%. Then (2R,3S)-4-phenyl-3-(N-Boc-amino)-1-oxirane-butane(1) was synthesized from compound 6 through reduction and cyclization with a yield of of 85.7% and a chromatographic purity of 99%. The affecting factors including the reaction temperature, the kinds of the base and the reductant were studied. The structures of the compound 1 and intermediates were characterized by 1H NMR, 13C NMR and ESI-MS. The preparation process was simple in operation, low in raw material cost, high yield.
Key words:atazanavir sulfate; intermediate; reduction; cyclization
