反応手順
5-(R)-Chloromethyloxazolidine-2-one (prepared according to [Danielmeier et al. Efficient Pathways to (R)- and (S)-hydroxymethyl-2-oxazolidinone and some derivatives. Tetrahedron: Asymmetry. 1995, vol. 6, pp. 1181-1190] (5 mmol) is reacted with sodium azide (7-10 mmol) in acetone (ca. 40-50 mL) at r.t. for ca. 24 h (until the reaction is completed). Solids are filtered off, and supernatant evaporated under vacuum to afford the product which is immediately used for the next step. Optionally, the synthesis is performed in dry N,N-dimethylformamide under inert atmosphere with sodium azide (5-10 mmol) or tetrabutylammonium azide (5-10 mmol), and the resulting solution of the crude 5-(S)-azidomethyloxazolidine-2-one is employed for the next step without solvent removal.
