Patent number: 5789599Abstract: Novel N-sulfinyl-2-carboxyaziridine compounds and novel N-hydrogen-2-hydroxymethylaziridine compounds are provided. The asymmetric synthesis of N-sulfinylaziridines is readily accomplished in high diastereomeric purity and good yield by the Darzens-type reaction of the metal enolate of an .alpha.-haloester and an enantiopure sulfinimine. Ring-opening of these aziridines affords .alpha.-amino acids and the otherwise difficult to prepare syn-.beta.-hydroxy-.alpha.-amino acids, both key structural units found in many bioactive materials. The N-sulfinyl radical may be selectively removed from the novel aziridine compounds by treatment with acid or base. Alternatively, the N-sulfinyl radical may be oxidized to provide the corresponding N-sulfonyl-aziridine, or reduced to form the corresponding 1H-2-hydroxymethylaziridine, either of which may subsequently be ring-opened to provide precursors to bioactive compounds.Type: GrantFiled: May 6, 1994Date of Patent: August 4, 1998Assignee: Drexel UniversityInventors: Franklin A.
