Chemistry 3BL Special Literature Project An Interpretation of the Scientific Research Article: “Palladium-Catalyzed Asymmetric [3 + 2] Trimethylenemethane Cycloaddition Reactions” by: Barry M. Trost,* James P. Stambuli, Steven M. Silverman, and Ulrike Schworer from Stanford University, published in The Journal of the American Chemical Society Atif Saleem GSI: Jason Hudak 28 April 2009 Chemistry 3B In the article titled “Palladium-Catalyzed Asymmetric [3 + 2] Trimethylenemethane Cycloaddition Reactions” written by Barry M. Trost et al. , the duty of the transition metal Palladium is described in terms of a [3+2] cycloaddition reaction. Cycloaddition reactions are

Saleem, Atif classified as the adding of two π bonds to create two σ bonds to form a resultant cyclic molecule. The [3+2] cylcoaddition which is explored through this paper is similar to the Diels- Alder reaction as seen in Chemistry 3B. The [3+2] cycloaddition of trimethylenemethane, (or TMM) is asymmetric and can be sped up by Palladium to yield a substituted cyclopentane. The first proposed mechanism of this reaction starts out with Ln-Pd(the transition metal
