Macrophomate synthase is no longer thought to catalyze this type of reaction, though Romesburg's catalytic antibodies and Seelig's ribozymes have been shown to catalyze it in vitro.
Macrophomate synthase is no longer thought to catalyze this type of reaction, though Romesburg's catalytic antibodies and Seelig's ribozymes have been shown to catalyze it in vitro. The first organic reaction to be understood by the Woodward-Hoffmann rules, it can only occur when one of its reactants is free to enter the s-cis conformation, and when a carbonyl compound is used as a reactant, a pyranoid species can be formed. Frontier molecular orbital theory is useful for understanding why this reaction's products prefer the endo position. One use of this reaction is the production of cyclohexene from ethene and butadiene. FTP, name this reaction of a diene and a dienophile whose two discoverers shared the 1950 Nobel Prize in Chemistry.
