(a) Interpretation: Consider the given synthetic schemes I and II, both of which produce the same eight-carbon target. For each synthesis scheme, it is to be determined whether it is linear or convergent. Concept introduction: A linear synthesis is a synthesis composed of sequential steps. In a convergent synthesis, portions of a target molecule are synthesized separately and are assembled together at a later stage.

Interpretation Introduction

(a)

Interpretation:

Consider the given synthetic schemes I and II, both of which produce the same eight-carbon target. For each synthesis scheme, it is to be determined whether it is linear or convergent.

Concept introduction:

A linear synthesis is a synthesis composed of sequential steps. In a convergent synthesis, portions of a target molecule are synthesized separately and are assembled together at a later stage.

Interpretation Introduction

(b)

Interpretation:

Consider the given synthetic schemes I and II, both of which produce the same eight-carbon target. For each synthesis scheme, assuming that each synthetic step proceeds with an 80 % yield, the overall percent yield is to be computed.

Concept introduction:

For a linear synthesis, the overall percent yield is equal to the product of the yields of each individual steps. For convergent synthesis, the overall percent yield is equal to the product of the yields of the steps of the longest branch of the synthesis.
