enolate उदाहरण वाक्य

उदाहरण वाक्य

1. The enolate intermediate discussed earlier is stabilized by residues additional hydrogen bonds to Tyr199 and Asn148.
2. It rather promotes conjugate addition by binding to the zwitterionic enolate, and stabilizing these intermediates.
3. Z must be powerful enough to facilitate deprotonation to the enolate ion even with a mild base.
4. Crossed Claisen condensations, in which the enolate and nucleophile are different esters, are also possible.
5. The trimethylsilyl enol ethers can also be used as masked enolate equivalents in the Mukaiyama aldol addition.
6. In the scheme shown, the enol or enolate of a methyl ketone reacts with an aldehyde.
7. Competing work with lithium enolate aldol reactions was published also in 1973 by Herbert O . House.
8. The enolate anion exhibits significant delocalization, and the highest electron density is on the second carbon.
9. Because carbonyl compounds are only weakly acidic, a strong base is needed for enolate ion formation.
10. In this reaction the rate-limiting step is formation of the enolate by deprotonation of the ketone.
