Abstract:
Use of transition metal compounds or complexes as catalysts or reagents in organic
synthesis is an exciting field in research and numerous novel reactions which are
impossible to achieve by conventional synthetic methods have already been
discovered. Total syntheses of many complex molecules have been achieved
efficiently in shorter steps, which was unbelievable ten years ago. So the applications
of transition metal-catalysts and reagents to organic synthesis are still being actively
investigated. Substituted pyran and furan represent a common structural component of
naturally occurring and biologically active molecules.
