Predict the stereochemistry of the epoxide formed when geraniol is treated with , (+)-diethyl tartrate (DET), and -butyl hydroperoxide (TBHP). Key Concept: Enantioselective Synthesis. The Visual Tool: Use the "Sharpless Mnemonic" (the 2D rectangle model). The Solution Hint:

Mixes Diels–Alder, bridgehead substitution constraints, and stereochemical memory. A disconnection reveals a [4+2] cycloaddition followed by a stereospecific alkylation impossible via direct enolate. advanced organic chemistry practice problems

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. Predict the stereochemistry of the epoxide formed when
