Wang, Dengjin published the artcileSynthesis of an anti-α-amino epoxide by one-carbon homologation of an α-amino ester: (2S,3S)-1,2-epoxy-3-(Boc-amino)-4-phenylbutane, SDS of cas: 5034-06-0, the publication is Organic Syntheses (2007), 58-67, database is CAplus.
The title compound was prepared by homologation of (S)-PhCH2CH(NHBoc)CO2C6H4NO2-4 with Me2S(O):CH2, conversion to (S)-PhCH2CH(NHBoc)CO2CH2Cl with HCl, and cyclization with LiAlH(OCMe3)3. Several other chloro ketones were also prepared
