-
A.
Sharpless epoxidation
chosen
Sharpless epoxidation is a landmark asymmetric oxidation reaction in organic chemistry that enables the enantioselective conversion of allylic alcohols to epoxides using chiral catalysts.
-
B.
Sharpless asymmetric dihydroxylation
Sharpless asymmetric dihydroxylation is a landmark chemical reaction that uses chiral catalysts to add two hydroxyl groups across an alkene with high enantioselectivity, revolutionizing asymmetric synthesis in organic chemistry.
-
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.
Corey–Winter olefin synthesis
Corey–Winter olefin synthesis is an organic reaction that converts 1,2-diols into alkenes via cyclic thiocarbonate intermediates, widely used for stereospecific formation of double bonds.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
