Autor: Richard J. Stoodley, Clive M. Raynor, Mark Smith, Richard P.C. Cousins, Robin G. Pritchard

Publikováno v: Tetrahedron Letters. 43:489-492

The facial reactivity of I towards electron-deficient aldehydes can be controlled by Ln(fod)3 catalyst selection, providing the basis of a route to glycals of type II [using Yb(fod)3] or III [using La(fod)3] where R = 4-nitrophenyl, 5-nitrofur-2-yl,

Synthesis and allylic reactivity of α-bromomethyl β-(2,3,4,6-tetra-O-acetyl-β-d-glucopyranosyl)oxy α,β-unsaturated carbonyl compounds

Autor: A. M. Freitas, Clive M. Raynor, Ana Paula Esteves, Richard J. Stoodley

Publikováno v: Tetrahedron Letters. 39:8353-8356

Under radical conditions, N -bromosuccinimide converts α-methyl β-(2,3,4,6-tetra- O -acetyl-β- d -glucopyranosyl)oxy α,β-unsaturated carbonyl compounds into their α-bromomethyl derivatives. The bromides undergo nucleophilic displacement reactio
