Chapter 19, Problem 19.67P

Interpretation Introduction

Interpretation:

For the given reaction, the missing intermediate and reagents are to be determined.

Concept introduction:

MCPBA is an oxidant that converts an alkene to an epoxide. Grignard reagent is used to open the epoxide rings under basic conditions by using ${\text{S}}_{\text{N}}\text{2}$ mechanism. The $\text{tert-butyldimethylsilyl chloride}$ (TBDMS-Cl) is the silyl ether protecting agent in the multistep organic synthesis. $\text{Tetra-n-butyl ammonium fluoride}$ (TBAF) i.e. ${\text{Bu}}_{\text{4}}\text{NF}$ is used to remove silyl ether protecting groups.
