Research
Dr.
Kellen-Yuen’s research interest lie in the area of
“green” organic synthesis of heterocyclic compounds, which entails the
modification of standard synthetic techniques in ways which reduce the
environmental impact and waste generated in traditional syntheses. To this end, most of her group focuses on
reactions which are solvent-free and/or are driven by microwave heating
methods. Examples of recent work in her
group include
the microwave synthesis of 2,3,4-trisubstituted pyrroles,
1,2,3-triazoles, and
indoles.
In addition, Dr.
Kellen-Yuen has an
interest in developing green syntheses which can be incorporated into
the undergraduate teaching labs. These reactions include
microwave-driven syntheses which utilize a common, household microwave
and standard laboratory glassware to make them easy to incorporate into
any teaching lab. To date, microwave-driven Wittig, Darzens,
Fisher
Indole and Fisher Esterification reactions have been developed, and
most run successfully in the teaching labs here at CSUS and at ARC.
