Abstract

Pd-catalyzed arylations of 2-exo-cyano-7-oxabicyclo[2.2.1]hept-5-en-2-endo-yl acetate and 7-oxabicycio[2.2.1]hept-5-en-2-one are regio- and stereoselective giving products of H-2(HCOOH) and Me(3)SiC=H coupling in which the aryl group (4-MeOC(6)H(4)) prefers the exo position of C(5) whereas the Pd-catatyzed vinylations with methyl-2-iodoacrylate prefers the exo position of C(6) center.

Organic synthesis

Organic synthesis is a special branch of chemical synthesis and is concerned with the intentional construction of organic compounds. Organic molecules are often more complex than inorganic compounds, and their synthesis has developed into one of the most important branches of organic chemistry. There are several main areas of research within the general area of organic synthesis: total synthesis, semisynthesis, and methodology.

Chemical reaction

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.

Aryl group

In organic chemistry, an aryl is any functional group or substituent derived from an aromatic ring, usually an aromatic hydrocarbon, such as phenyl and naphthyl. "Aryl" is used for the sake of abbreviation or generalization, and "Ar" is used as a placeholder for the aryl group in chemical structure diagrams, analogous to “R” used for any organic substituent. “Ar” is not to be confused with the elemental symbol for argon. A simple aryl group is phenyl (), a group derived from benzene.
