Synthesis of three cis-trans pairs of N-sulfonylated-2-aziridinemethanols starting from (S)-threonine, (R)-allothreonine, a chiral 2-amino alcohol, or enantiomerically enriched 2, 3-epoxy alcohols is described. A synthetic route to N-tosyl- and N-mesyl-2-aziridinemethanols from (R)- and (S)-serines is also presented.
An aza-Payne rearrangement-epoxide ring opening reaction of 2-aziridinemethanols in a one-pot manner: A regio- and stereoselective synthetic route to diastereomerically pure N-protected 1,2-amino alcohols
A regio- and stereoselectivesyntheticroute to diastereomericallypure1,2-aminoalcohols via a one-potaza-Payne rearrangement - epoxide ringopeningreaction of 2-aziridinemethanols is reported.
A one-pot aza-Payne rearrangement-epoxide ring opening reaction of 2-aziridinemethanols: A regio- and stereoselective synthetic route to diastereomerically pure 1,2-amino alcohols
A regio- and stereoselectivesyntheticroute to diastereomericallypure1,2-aminoalcohols via a one-potaza-Payne rearrangement — epoxide ringopeningreaction of 2-aziridinemethanols is reported. Satisfactory yields are obtained in excellent diastereoisomeric excesses by successive exposure of 2-aziridinemethanols to potassium hydride and nucleophilic reagents in a one-potmanner.
