Test your knowledge with these representative advanced problems. (Solutions are discussed conceptually below). Problem 1: Predicting the Diastereomer
In my synthesis, am I using the most efficient route, or am I adding and removing protecting groups unnecessarily? Recommended Resources for Further Practice advanced organic chemistry practice problems
Modern synthesis relies heavily on transition metals. Mastery of the catalytic cycles for Palladium-catalyzed cross-couplings (Heck, Suzuki, Stille) and Olefin Metathesis (Grubbs) is non-negotiable. 4. Retrosynthetic Analysis advanced organic chemistry practice problems
You are reacting (S)-2-phenylpropanal with methylmagnesium bromide (MeMgBr). Task: Use the Felkin-Anh model to predict the major diastereomer formed. Draw the transition state and explain why the nucleophile attacks from a specific face. Problem 2: Pericyclic Mechanisms advanced organic chemistry practice problems
Is my nucleophile attacking the least hindered face, or is there an electronic effect (like chelation control) override?
