Chapter 13, Problem 33P

(a)

Interpretation Introduction

Interpretation:

To determine the number of deuterium atoms that are incorporated in palmitic acid if CD3COSR and nondeuterated malonyl thioester are used as starting materials.

Concept introduction:

For the synthesis of arachidic acid, in first step acetyl thioester and malonyl thioester undergoes Claisen condensation. The product of Claisen condensation undergoes reduction, dehydration and a second reduction to form a four-carbon thioester.

The four carbon thioester combines with another molecule of malonyl thioester and undergoes Claisen condensation, reduction, dehydration and a second reduction to form a six carbon thioester. The reaction can proceed to form a fatty acid of an even number of carbon atoms and repetition of sequence adds two carbon.

(b)

An organic chemistry Teaching Assistant (TA) suggested in your last discussion section that there is only one major organic product of the following reaction and that this reaction builds a ring. If the TA is right, draw the product in the drawing area below. If the TA is wrong, just check the box below the drawing area. NaOH ?
A student suggests that the molecule on the right can be made from a single molecule that doesn't have a ring. If the student is correct, draw the starting material below, otherwise, check the box under the drawing area. Click and drag to start drawing a structure. : ☐ + NaOH टे
