Chapter 11, Problem 11.62AP
Interpretation Introduction

(a)

Interpretation:

The synthesis of ORGANIC CHEMISTRY SAPLING ACCESS + ETEX, Chapter 11, Problem 11.62AP , additional homework tip  1in enantiomerically pure form from enantiomerically pure ORGANIC CHEMISTRY SAPLING ACCESS + ETEX, Chapter 11, Problem 11.62AP , additional homework tip  2is to be stated.

Concept introduction:

When an allylic alcohol is reacted with enantiomeric tartrate esters, ORGANIC CHEMISTRY SAPLING ACCESS + ETEX, Chapter 11, Problem 11.62AP , additional homework tip  3and ()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, DET, used. The epoxide formed undergoes stereospecific ring opening reactions.

Interpretation Introduction

(b)

Interpretation:

The synthesis of (2R, 3S)-3-methoxybutan-2-one in enantiomerically pure form from enantiomerically pure (2R, 3R)-2, 3-dimethyloxirane is to be stated.
