Isovanillin derived N-(un)substituted hydroxylamines possessing an ortho-allylic group: valuable precursors to bioactive N-heterocycles.
The intramolecular 1,3-dipolar cycloaddition of isovanillin derived N-aryl hydroxylamines possessing ortho-allylic dipolarophiles affords novel benzo analogues of tricyclic isoxazolidines that can be readily transformed into functionalized lactams, γ-aminoalcohols and oxazepines. The corresponding N-unsubstituted hydroxylamines give rise to tetrahydroisoquinolines. Anxiogenic properties of thes...
متن کاملSynthesis of saturated N-heterocycles.
Saturated N-heterocycles are prevalent in biologically active molecules and are increasingly attractive scaffolds in the development of new pharmaceuticals. Unlike their aromatic counterparts, there are limited strategies for facile construction of substituted saturated N-heterocycles by convergent, predictable methods. In this Synopsis, we discuss recent advances in the synthesis of these comp...
متن کاملA new, mild one-pot synthesis of iodinated heterocycles as suitable precursors for N-heterocyclic carbene complexes
N-heterocyclic carbenes (NHCs) have been shown to be versatile ligands for transition metal complexes. Most importantly, these ligands have an outstanding impact on many homogeneous catalysts, often outperforming more common phosphine ligands. Metal coordination to NHCs has been achieved by a variety of methods. Among these, oxidative addition is particularly attractive because of the typically...

Unsaturated O- and N-heterocycles from carbohydrate feedstocks.
With reference to the impending transition of chemical industry from depleting fossil raw materials to renewable feedstocks--the end of cheap oil is predicted for 2040 at the latest--this account gives an overview on chemically transforming carbohydrates, by far the major part of the annually regrowing biomass, into the following unsaturated O- and N-heterocycles with versatile industrial appli...
