Abstract
A series of conjugate addition reactions have been performed with vinyl-substituted N-heterocycles in acid-catalyzed conversions. Using active methylene compounds, double conjugate addition reactions have been accomplished to provide dipyridyl and related heterocyclic products. These conversions have utilized 1,3-dicarbonyl compounds, cyano esters, a cyano sulfone, and malonyl nitrile as nucleophiles. The Michael accepting groups include vinyl-substituted pyridines, quinoline, and pyrazine. Double conjugate addition reactions have also been accomplished with 2,6-divinylpyridine and related systems.

Abstract
Benzoxazole, 1,2-benzisoxazole and 2,1-benzisoxazole are biologically active molecules with potential applications in drug design. Their interaction with aqueous medium in biological systems may be simulated by considering their interaction with explicit water molecules. Such studies provide information on the structures, energies and type of interactions stabilizing the resulting geometric systems. The objective of the current study was to utilize theoretical approaches to investigate the structures, stabilization energy and binding energy of benzoxazole–water, 1,2-benzisoxazole–water and 2,1-benzisoxazole–water complexes. The calculations were performed utilizing the density functional theory (DFT)/M06-2X/6-311 ++ G(d,p) method and the DFT/ωB97XD method with both the 6-311 ++ G(d,p) and the aug-cc-pVDZ basis sets. The results suggest that the stability of the different clusters depends on interrelated factors including the rings formed by intermolecular hydrogen bonds and the proton affinity (PA) or acidity of the atoms forming the intermolecular hydrogen bonds with the water molecules. A comparison across methods indicates that the results follow similar trends with different methods.
