  1. Honors Organic Chemistry Laboratory Larry Augenstein and Allen M. Schoffstall Department of Chemistry University of Colorado at Colorado Springs Spring Semester, 2007

  2. Honors apply for candidacy to the honors section, a second semester organic laboratory course. Students are responsible for organizing, initiating, orchestrating and completing the one-semester honors laboratory course. Students are expected to establish their own research goals with the assistance and guidance of the instructional team.

  3. Overview • Laboratory learning goals and experiments • Choice of projects • Start by using articles from J. Chem. Ed. • Projects • History and background • Focus for the laboratory • Scope; mechanistic, synthetic

  4. Overview • Main expectations of students • Planning stage • Perform synthetic procedures • Perform characterization • Perform application of the synthetic product • Student Outcomes

  5. Plan for Projects (Main Steps) • Meet to discuss possible projects(1/17). • Pick a project; locate articles, do readings • Do first 6 labs same as traditional section • Submit preliminary proposal (2/5) • Submit final proposal with timeline (2/25) • Do project; modify timeline as necessary. • Prepare and present a research poster (4/23)

  6. Some Possible Projects • Flutamide synthesis • Guaifenesin synthesis • Trihalobenzene • Chalcones • Azide cyclization • Sunscreen synthesis • Prozac synthesis • Barbier Reaction • Williamson reactions • Heck reactions • Cinnamate ester • Oxone epoxides

  12. Student Response • Used for one semester in the Spring of 2006 • Students have responded very favorably to the projects. • Very good learning experience • Very good student-teacher interaction • Insight into how research is conducted • Learning new instrumentation • Student autonomy

  13. Observations • Honors project experiments have merit for the organic chemistry laboratory. • Students can be invigorated by participating in an honors project. • The student presentations provide a culminating experience for students.
