Levodropropizine, an antitussive drug, was prepared in high enantiomeric excess in three steps, starting from dichloroacetone (2). Monosubstitution of 2 with sodium benzoate and subsequent baker's yeast reduction stereoselectively afforded the corres

Reduction with baker's yeast of ethyl or methyl 4-chloro-3-oxobutanoate in the presence of allyl bromide or allyl alcohol as additive afforded the corresponding L- and D-3-hydroxyesters. Several reduction conditions were tested, involving: different

The Amano PS lipase-catalyzed acetylation of 2-hydroxymethylaziridines 1a–e has been investigated in order to evaluate the effect of ring substituents on the enantioselectivity of the reaction and to assess the stereochemical preference of the enzy

The nucleophilic ring opening of trans-aziridine-2,3-dicarboxylate 1 and substituted N-acyl-, N-(methoxycarbonyl)-, and N-(methanesulfonyl)aziridine-2,3-dicarboxylates 2−4 allows an easy synthetic approach to β-hydroxy, β-amino, β-(alkylthio), a

(S)-(−)-N-acetyl-2-methoxycarbonylaziridine 1 undergoes easy ring-opening by Bronsted acids or nucleophiles in the presence of a Lewis acid catalyst. The regioselectivity is not always exclusive, affording optically active α- and β-aminoacids.
