Mt. Diaz et al., Convergent synthesis of trans-fused oxane ring systems based on Ni-II/Cr-II-mediated cross-coupling reactions, SYNLETT, (3), 2001, pp. 345-348
A general method for the convergent assembly of polyether structures has be
en developed based on a Ni-II/Cr-II-mediated cross-coupling reaction of alk
enyl iodides with aldehydes. The present method allowed coupling to oxane r
ings via acetal cyclization and reductive etherification reactions.
