D. Stereochemistry and Conformational Analysis (3 problems) 19. Using Newman projections and chair conformations, determine the most stable conformation of trans-1-tert-butyl-4-methylcyclohexane and predict major product from hydrogenation if relevant. 20. Assign absolute configuration for the product formed by Sharpless asymmetric epoxidation of (E)-2-hexenol using (+)-DET; show how the mnemonic applies. 21. For epimerizable α-chiral ketone, predict product ratios under thermodynamic vs kinetic enolate formation and justify with pKa and sterics.
: Predict the major product when a Grignard reagent is treated with a titanium/iron heterobimetallic species followed by two different electrophiles (e.g., cap C cap O sub 2 and an alkyl iodide). Key Concept
He erased a hole in his paper. He was running out of time. 45 minutes left. He was still stuck on step three of the synthesis. He had three more problems to go, each looking more terrifying than the last. Problem #15 was a total synthesis of a molecule that had only been discovered three months ago.
: This is one of the most rigorous exams globally for advanced organic chemistry. You can access Paper 1 with Solutions on Vedantu , which includes detailed explanations for complex mechanisms.
This guide focuses on high-level practice problems. We will cover mechanisms, synthesis, and spectroscopy. 🔬 Core Advanced Organic Chemistry Topics
