Abstract:
A series of substituted arylidene thiazoles were allowed to react with Wittig-Horner (WH) reagent, tetraethyl methyl-1,1-bisphosphonate, to produce via Michael addition reaction the corresponding heteroarylmethylenebisphosphonates (BPs) in different yields according to the experimental conditions. Acid hydrolysis of the new BPs was undertaken to obtain the corresponding bisphosphonic acids. Prediction and the in vivo activity of the products in the rat adjuvant model are also discussed in terms of structure-activity relationships (SAR).

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
