A versatile scaffold for a library of liposidomycins analogues: a crucial and potent glycosylation step
摘要:
A key step for the synthesis of a diazepanone scaffold dedicated to a library of MraY inhibitors is described. It involves the O-glycosylation of a conveniently protected L-serine by a D-ribofuranose derivative. High yield and selectivity were obtained. (C) 2003 Elsevier Ltd. All rights reserved.

Abstract The reaction of indole with a glycosyl halide containing a non-participating group at position 2 in the presence of silver oxide and molecular sieve in dry benzene yielded an O-substituted 3-glycosylindole (indole C-nucleoside). 2,3,4,6-Tetra-O-benzyl- d -glucopyranosyl bromide and 6-nitroindole gave anomeric per-O-benzylated 3- d -glucopyranosyl-6-nitroindoles; from 2,3,5-tri-O-benzyl- d

furanosylation method promoted by phenanthroline catalysts under mild and operationally simple conditions. NMR experiments and density functional theory calculations support an associative mechanism in which the rate-determining step occurs from an inverted displacement of the faster-reacting phenanthrolinium ion intermediate with an alcohol nucleophile. The phenanthroline catalysis system is applicable
