Chapter 13, Problem 13.37P

Interpretation Introduction

Interpretation:

Whether the given generic synthesis scheme is linear or convergent is to be determined. The overall percent yield is to be computed.

Concept introduction:

In a convergent synthesis, portions of a target molecule are synthesized separately and are assembled together at a later stage. The overall percent yield in a convergent synthesis like this is the product of the yields of the longest branch of the synthesis with the lowest yields.

In a linear synthesis, portions of a target molecule are synthesized in sequential steps. For a linear synthesis, the overall percent yield is equal to the product of the yields of the individual steps.
