Synthesis and use of achiral oxazolidine-2-thiones in selective preparation of trans 2,5-disubstituted tetrahydrofurans
Jalce, Gael,Franck, Xavier,Figadere, Bruno
body text, p. 378 - 386 (2009/09/25)
The use of achiral N-acetyloxazolidine-2-thiones in the C-glycosylation of lactol acetates has allowed us to prepare with high diastereoselectivity the expected trans 2,5-disubstituted tetrahydrofurans. A study based on the role of the steric hindrance of the N-acetyloxazolidine-2-thiones is reported. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.
