Target entity: Corey–Itsuno reduction Context triple: [Corey–Bakshi–Shibata reduction, relatedTo, Corey–Itsuno reduction]
-
A.
Corey–Bakshi–Shibata reduction
The Corey–Bakshi–Shibata reduction is a widely used asymmetric organic reaction that enantioselectively reduces ketones to chiral alcohols using a chiral oxazaborolidine catalyst and borane.
-
B.
Bechamp reduction
Bechamp reduction is an organic redox reaction in which nitro compounds are reduced to amines using iron and acid, historically important in the industrial production of anilines and related aromatic amines.
-
C.
Corey–Kim oxidation
Corey–Kim oxidation is an organic chemistry reaction that converts primary and secondary alcohols into aldehydes and ketones using N-chlorosuccinimide and dimethyl sulfide under mild conditions.
-
D.
Eschenmoser sulfide contraction
Eschenmoser sulfide contraction is an organic rearrangement reaction that converts certain sulfur-containing intermediates into carbonyl compounds, widely used in complex molecule and natural product synthesis.
-
E.
Barton–McCombie deoxygenation
Barton–McCombie deoxygenation is an organic chemistry reaction that converts alcohols into the corresponding hydrocarbons via radical-mediated removal of the hydroxyl group.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
