Chapter 5, Problem 52P

(a)

Interpretation Introduction

Interpretation:The natural ()-menthol with 1R,2S,5R- stereochemistry should be identified from the possible stereoisomers that exist for ()-menthol .

Concept introduction: ()-menthol is also known as laevo-menthol . It is naturally found in the aroma of peppermint and is used as essential oil. The structure of ()-menthol has three chiral centers and hence total eight stereoisomers exist for menthol as illustrated below.

Interpretation Introduction

Interpretation: The natural (+)-neomenthol with 1S,2R,5R- stereochemistry should be identified.

Concept introduction: ()-menthol is also known as laevo-menthol . It is naturally found in the aroma of peppermint and is used as essential oil. The structure of ()-menthol has three chiral centers and hence total eight stereoisomers exist for menthol as illustrated below.

(c)

Interpretation Introduction

Interpretation: The stability order for the three diastereomers namely menthol, isomenthol, and neomenthol should be determined.

Concept introduction:In chair form all the C—C—C bond angle are 109.5 ° . Since this is ideal tetrahedral angle so there is no angular strain in chair form. The staggered C—H

bond further allows for no amount of torsional strain. There are two kinds of hydrogens in cyclohexane namely axial and equatorial indicated as follows:

First image: I have to show the mecanism (with arows and structures) of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary Second image: I have to show the mecanism (with arrows and structures) for the reaction on the left, where the alcohol A is added fast in one portion its not an exam
