Interpretation Introduction

Interpretation:

The compounds $A$, $B$, $C$, $D$ are to be identified.

Concept introduction:

When an allylic alcohol is reacted with enantiomeric tartrate esters, $(+)\text{DET}$ and $(-)\text{DET}$, in presence of titanium (IV) isopropoxide catalyst and tert-butylhydroperoxide, two enantiomeric epoxides are formed. This reaction is known as Sharpless asymmetric epoxidation reaction. The epoxide is formed at the double bond present in the allylic alcohol. The stereochemistry of the enantiomeric epoxide products depends upon the stereochemistry of the tartrate ester, $\text{DET}$, used.
