Wang, Dengjin; Nugent, William A. published an article in 2007, the title of the article was Synthesis 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.Recommanded Product: trimethyloxosulphonium chloride And the article contains the following content:
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 The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Recommanded Product: trimethyloxosulphonium chloride
The Article related to aminophenylethyloxirane preparation chloro ketone intermediate, Heterocyclic Compounds (One Hetero Atom): Ethylene Oxides and other aspects.Recommanded Product: trimethyloxosulphonium chloride
