Chapter 25.3, Problem 19CC

(a)

Interpretation Introduction

Interpretation:

The alkenes required for the synthesis of given set of amino acids by asymmetric catalytic hydrogenation need to be identified.

Concept introduction:

Asymmetric catalytic hydrogenation is a reaction in which the alkene substrate is reduced to a saturated compound by addition of two atoms of hydrogen.  When chiral catalyst is used a enantioselective product is obtained.  This technique uses a chiral catalyst so that the amino acids can be prepared with high enantiomeric excess.

The final step after hydrogenation is the hydrolysis of the protected group of amine.  The general scheme can be shown as,

To find: the alkene taken for the synthesis of L-alanine using asymmetric catalytic hydrogenation.

In an effort to reduce costs and increase the accessibility of instruments that utilize spectrophotometric detection, some researchers are beginning to experiment with 3D-printed parts. One example of this is the 3D-printed flow cell, shown at right. This device was made using polylactic acid and accommodates a LED at one end and a detector at the other. It can be used for standalone flow injection spectrophotometry or coupled to a chromatographic separation to be used as a detector.  Explain why the sensitivity varies with the length of the flow cell, as shown in the data below. Could this setup be used for fluorescence analysis? Why or why not?
The dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines:  the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the spectrum. This discovery eventually spawned atomic absorption spectrometry, which became a routine technique for chemical analysis in the mid-20th century. Laboratory-based atomic absorption spectrometers differ from the original observation of the Fraunhofer lines because they have always employed a separate light source and atomizer. This article describes a novel atomic absorption device that employs a single source, the tungsten coil, as both the generator of continuum radiation and the atomizer of the analytes. A 25-μL aliquot of sample is placed on the tungsten filament removed from a commercially available 150-W light bulb. The…
