This paper reports the development of an effective synthetic protocol between 1,3- organo-propynones 1 and different diorganoyl dicalcogenides 2 mediated by Selectfluor® and employing acetonitrile as a solvent, at room ...

Three different intramolecular Diels-Alder (IMDA) reactions associated with the formation of fused and bridged tricyclodecane skeletons have been studied at the B3LYP/6-31G(d) computational level. While substitution on ...

The nucleophilic aromatic substitution reaction of benzohydrazide derivatives towards 2-chloro-5-nitropyrimidine is used as model system to experimentally and theoretically show that intramolecular hydrogen-bond formation ...

The spanning-tree approximation model is one of the models used for polymerizations with intramolecular reaction regardless of the size of the ring formed. We present a modification of this model that uses more accurate ...

This paper reports the study developed for the preparation of 1-(butylselanyl)-2-phenyl-4H-selenopheno[2,3-c]chromenes substituted by cyclization in intramolecular cascade of arylpropargyl ethers. Firstly, the study was ...
