TBAT-mediated nitrone formation of ω-mesyloxy-O-tert-butyldiphenylsilyloximes: Facile synthesis of cyclic nitrones from hemiacetals

Tamura, Osamu,Toyao, Atsushi,Ishibashi, Hiroyuki

, p. 1344 - 1346 (2007/10/03)

Chiral and cyclic nitrones were synthesized by TBAT-mediated desilylative cyclization of ω-mesyloxy-O-tert-butyl-diphenylsilyloximes, readily prepared from sugar derivatives by a consecutive treatment with O-tert-butyldiphenylsilylhydroxylamine and with m
