HALOENAMINES - II. A RAPID AND EFFICIENT SYNTHESIS OF CARBOHYDRATE 1,2-ORTHOESTERS
Ernst, Beat,Mesmaeker, Alain De,Wagner, Beatrice,Winkler, Tammo
, p. 6167 - 6170 (2007/10/02)
Carbohydrate exo 1,2-orthoesters are obtained in good to excellent yields by treating furanose and pyranose hemiacetals first with 1.1 eq. 1-chloro-2,N,N-trimethyl-propenylamine and then with the appropriate alcohols in the presence of NEt3.
