Synthesis of oxazolinyl aziridines

Tetrahedron Letters, 1999
Abstract Aziridinyllithiums 4a and 4b , which are stable at low temperature, can be generated by deprotonation of 3a and 3b . Oxazolinyl aziridines 5a-j and 6a-b have been prepared by the reaction of oxazolinyl aziridinyllithiums 4a and 4b with electrophiles. Aziridines 6c and 6d were, instead, synthesized by a Darzens-like reaction

Formation of Scalemic Aziridines via the Nucleophilic Opening of Aziridines

The Journal of Organic Chemistry, 1997
Introduction As part of our work in the preparation of aziridineallylsilanes1 we had need of a method for the preparation of simple monosubstituted, scalemic aziridines such as 1. The preparation of scalemic aziridines has been well covered in a number of reviews.2 Two methods seemed particularly well suited for the preparation of the types of ...

Asymmetric Catalytic Aziridination to Synthesize Spiro‐aziridine Oxindoles

Chemistry – A European Journal
AbstractAsymmetric catalytic aza‐Michael‐initiated ring closure of methyleneindolinones with N‐tosyloxycarbamates has been established. The reaction using a chiral nickel complex catalyst enabled the formation of a series of spiro‐aziridine oxindoles in good yields (up to 99 %) with high stereoselectivity (up to 97 % ee, >19 : 1 dr) under mild ...

A Sulfonyl-Substituted Aziridine

Acta Crystallographica Section C Crystal Structure Communications, 1996
In the title compd., 1-p-toluenesulfonylaziridine-(2S)-carboxylic acid tert-Bu ester, C14H19NO4S, the p-toluenesulfonyl substituent on the N atom and the ester substituent on one C atom of the aziridine ring are mutually trans, minimizing steric interactions.
