The mechanisms of the Fischer indole synthesis and competing cleavage pathways were explored with SCS-MP2/6-31G(d) and aqueous solvation calculations. Electron-donating substituents divert the reaction pathway to heterolytic N-N bond cleavage and preclude the acid-promoted [3,3]-sigmatropic rearrangement.

Alara Oner, Nihan Celebi-Olcum

Summary: This study predicts through computational methods that simple structural modifications in spiroligozymes can significantly increase the occupancy of hydrogen bonding, improving the rate of ester exchange reactions. It also highlights the importance of including an oxyanion hole motif for efficient catalysis.

Morita-Baylis-Hillman reaction: how do optimal enzyme active sites compare with organocatalysts

Tugce Utnier, Nihan Celebi-Olcum

Summary: The current study investigates the role of various catalytic motifs in the Morita-Baylis-Hillman reaction and shows that a bidentate oxyanion hole cooperating with an acid-base catalyst can stabilize multiple steps along the reaction pathway. The calculations also indicate the potential dual role of a guanidinium ion in stabilizing oxyanion intermediates and mediating the proton transfer. This study emphasizes the importance of a conformationally adaptable preorganized electrostatic environment in promoting such multistep transformations.
