Advanced Organic Chemistry Practice Problems ✦ [AUTHENTIC]

Consider 2-methylcyclohexanone treated with LDA at –78 °C, then quenched with methyl iodide, yielding Product A. The same ketone treated with NaH at 25 °C, then methyl iodide, yields Product B. Both products are monomethylated.

Problem

Predict the major enantiomer formed in the Sharpless Asymmetric Epoxidation of geraniol using (+)-diethyl tartrate (DET). Mental Framework: Use the "mnemonic square" to orient the allylic alcohol. advanced organic chemistry practice problems

To help you sharpen that intuition, here are three high-level practice concepts that frequently trip up even the best students, along with how to approach them. 1. The Pericyclic Puzzle (Diels-Alder & Beyond) then quenched with methyl iodide
