Chapter 13, Problem 63IP

Interpretation Introduction

Interpretation: The unknown compounds in the given reaction to be identified.

Concept Introduction:

Useful reagents:

1. a) $\text{ Vinylmagnesium bromide}$: A strong Nucleophile reacts with an epoxide in a ring-opening reaction, to attack the less substituted side.
2. b) $\text{NaH}$: is a source of hydride ion which acts as a strong base.
3. c) ${\text{OsO}}_{\text{4}}$: Dihydroxylation of the terminal alkene in the presence of NMO gives a mixture of diastereomeric diols.

To Identify: The unknown compounds in the overall reaction scheme to be predicted.
