Theoretical yield of diels alder reaction
Webb14 nov. 2012 · As described in Organic Chemistry by Carey (Section 10.12), the Diels-Alder reaction was discovered in 1928. This reaction forms a six-membered ring from two pieces: a conjugated "diene" (which provides four of the ring atoms) and a "dieneophile" (which provides two of the ring atoms). Webb19 juli 2011 · The Diels-Alder is a stereospecific reaction, because the stereochemistry of the dienophile is maintained in the cyclohexene product: a transdienophile yields in the …

Did you know?
In organic chemistry, the Diels–Alder reaction is a chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene derivative. It is the prototypical example of a pericyclic reaction with a concerted mechanism. More specifically, it is classified as a thermally-allowed [4+2] cycloaddition with Woodward–Hoffmann symbol [π… WebbWith optimized reaction conditions in hand, the para-prenylated dienophile 155 and diene 158 underwent a Diels–Alder cycloaddition reaction in the presence of (S)-VANOL as …
