Abstract
- The solid-phase ring-opening of N-nosyl aziridines under microwave conditions is described. Thus, p-nitrobenzenesulfonyl (nosyl = Ns)-activated aziridines 2a-g were prepared from1,2-amino alcohols 1a-g with an excess amount of nosyl chloride (NsCl) in CH2Cl2-pyridine (2:1). The ring-opening of the aziridines 2a-g with resin-bound amines 3-5 gave the corresponding amines 6-12 in >25 to >95% yield with 63-97% purity after acidic cleavage. The glycine and proline derivatives 16-18 were also obtained from 13-15 in >95% yield with 93-97% purity.
