Abstract
[reaction: see text] The reaction of 3-azido-2,3-dideoxy-hexopyranose compounds from the d-gluco, d-galacto, d-lacto, and l-arabino carbohydrate series, with (diacetoxyiodo)benzene and iodine, generated 2-azido-1,2-dideoxy-1-iodo-alditols with one carbon less than the starting carbohydrate. These beta-iodo azides could be transformed by dehydroiodination into vinyl azides, which in turn afforded 3-monosubstituted 2H-azirines under thermal conditions. These beta-iodo azides and 2H-azirines may be interesting chiral synthons for the preparation of more complex heterocyclic systems.

Abstract
Heterocyclization of functionalized vinylic derivatives of imidazo[1,2-a]pyridines was explored experimentally and theoretically using semiempirical AM1 and ab initio methods. A range of functionalized vinylic derivatives (azido, amino, and carbodiimide groups) were prepared for conversion into pyrroloazaindoles 19-22, imidazo[1,x]-, (x = 5, 6, 7, 8), [2,6]-, and [2,7]naphthyridines 28-30, 35-38 by thermal reaction. In the case of vinylic groups in the 5 position, peri annulation also was observed. The experimental and theoretical data are compared and discussed.

Abstract
An unprecedented attack of the azide functionality by iminium species, generated in situ under Vilsmeier conditions, provided a novel route for the construction of nitrogen heterocycles. Thus, the treatment of 2-azidoacetophenones with Vilsmeier reagent under reflux conditions gave 5-aryloxazole-4-carboxaldehydes. One-pot synthesis of oxazole carboxaldehydes from 2-bromoacetophenones by dehaloazidation-Vilsmeier cyclization reaction sequence provided better yields. The susceptibility of the carbonyl group to undergo chloroformylation at room temperature without affecting the azide function was exploited to provide an attractive scheme for the synthesis of alpha-azido-beta-chlorovinyl azides from phenacyl azides. The synthesis of a series of N-aryl 5-chloro-2-(dimethylamino)imidazole-4-carboxaldehydes was accomplished by the Vilsmeier cyclization of N-aryl-2-azidoacetamides. The possible mechanisms for the reactions are also discussed.
