Chapter 8.11, Problem 19P

Interpretation Introduction

Interpretation:

Thestructure of the alkene that could be used as a starting material in a preparation of synthetic disparlure is to be shown.

Concept introduction:

The reaction of alkene with peroxy acid is the epoxidation of alkene.

In epoxidation, the oxygen is bonded to two double bonded carbons and forms a three membered ring.

Epoxide is oxygen containing three membered ring.

Epoxidation in peroxy acid is the syn addition across the double bond.

Cis isomer of alkene, on epoxidation, gives a cis product, and trans isomer of alkene gives a trans product.
