Microwave-Mediated Synthesis of Lophine: Developing a Mechanism To Explain a Product   R. David Crouch, Jessica L. Howard, Jennifer L. Zile, and Kathryn H. Barker
Describes the microwave-mediated preparation of lophine (2,4,5-triphenylimidazole). The experiment also provides an opportunity for students to employ the principles of carbonyl chemistry in devising a mechanism to explain the formation of the product.

Isolation of Curcumin from Turmeric  Andrew M. Anderson, Matthew S. Mitchell, and Ram S. Mohan
The active ingredient in turmeric is curcumin, which is approximately 2% by weight of the root of turmeric. We have developed two simple procedures for isolation of curcumin from turmeric, making this a new and interesting natural product isolation experiment.
