A facile preparation of peracylated α-aldopyranosyl chlorides with thionyl chloride and tin tetrachloride
Wang, Qingbing,Fu, Jie,Zhang, Jianbo
, p. 2989 - 2991 (2008)
Aldopyranose peracetates react with thionyl chloride and tin tetrachloride, producing the corresponding peracylated aldopyranosyl chlorides in very good to excellent yields (88-100%) with exclusive α-anomeric selectivity and short reaction times. The use of peracylated sugars as the substrate in large scale reactions also proceeds in high yield. Crown Copyright
Highly stereoselective synthesis of peracylated α-aldopyranosyl chlorides from aldopyranose peracetates and thionyl chloride catalyzed by BiCl3 generated in situ from the procatalyst BiOCl
Ghosh, Rina,Chakraborty, Arijit,Maiti, Swarupananda
, p. 9631 - 9634 (2004)
Aldopyranose peracetates react with thionyl chloride and BiCl3, generated in situ from a substoichiometric amount of the procatalyst BiOCl, producing the corresponding peracylated aldopyranosyl chlorides in very good to excellent yields (82-97%
Indium(III) triflate-mediated one-step preparation of glycosyl halides from free sugars
Giri, Santosh Kumar,Kartha, K. P. Ravindranathan
, p. 3378 - 3383 (2010)
In(OTf)3 has been found to be an efficient catalyst for the direct conversion of reducing sugars to their respective acylated glycosyl halides in good yields under mild conditions. The glycosyl halides so obtained can be converted to alkyl glyc
Preparation of glycosyltriazenes
Weng, Min,Jochims, Johannes C.
, p. 530 - 536 (2007/10/03)
O-Unprotected glycosyltriazenes are prepared for the first time by coupling of 1-anthraquinone-1-diazonium hydrogensulfate with β-glycopyranosylamines to afford 1-(anthraquinone-1-yl)-3-(β-glycopyranosyl)triazenes 3a-h. Acetylation of compounds 3 furnished the O-acetates 4a-g. The stability of triazenes 3 results from fixation of the NH proton in an intramolecular hydrogen bond to one of the anthraquinone carbonyl oxgen atoms. Treatment of triazenes 4 with tert-butyl hypochlorite afforded acetoglycosyl chlorides 6 and 1-azidoanthraquinone 7. With acetic acid the triazene 4a formed tetra-O-acetyl-D-xylopyranose 9 together with 1-aminoanthraquinone 10. WIiley-VCH Verlag GmbH, 2000.
