dienophile उदाहरण वाक्य

उदाहरण वाक्य

1. Diels-Alder reactions occur between a conjugated diene and an alkene ( commonly known as the dienophile ).
2. Partially negative atoms on the diene will bond to partially positive atoms on the dienophile, and vice versa.
3. When the substituents of the dienophile are exo, there is no interaction between those substituents and the diene.
4. This weak acid forms a diester, it undergoes additions across the double bond, and it is an excellent dienophile.
5. For this reason, benzocyclobutadiene will readily dimerize or polymerize and it reacts as a dienophile in Diels-Alder reactions.
6. The relationship is only valid for the groups on the diene alone, or the groups on the dienophile, alone.
7. This is due to the alcohol precursor dehydrating under acidic conditions to produce both the diene and dienophile required for this reaction.
8. A pyranone was similarly used as the dienophile by K . C . Nicolaou's group in the total synthesis of taxol.
9. In intramolecular Diels-Alder Reaction, asymmetric induction can be induced through allylic 1, 3 strain on the diene or the dienophile.
10. One cannot predict, via this principle, whether a substituent on the diene will be syn or anti to a substituent on the dienophile.
