The N-t-butyl and N-benzyl aziridine carboxylic acid phenylthiol esters are deprotonated in the α-carbonyl position and alkylated by alkyl halides, by aldehydes, and by nitrostyrene. The diastereoselectivities in the additions to trigonal centers range from 72 to 88% (rel. topicity lk with benzaldehyde).
