Introduction The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1)‚ this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates‚ in a single step‚ which explains the stereospecificity due to substituents not being given the chance to “switch around”. (1)These six membered rings are synthesized by reacting a dienophile

Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance
