Predict the major product of the following thermal reaction and explain the stereochemical outcome using Frontier Molecular Orbital (FMO) theory. -octa-2,4,6-triene is heated to 150°C. Key Concept: Electrocyclic Ring Closure. Deep Dive: system under thermal conditions, is the rotation conrotatory disrotatory The Solution Hint: According to the Woodward-Hoffmann rules, a thermal

Predict the product and show the mechanism for the reaction of methyl vinyl ketone with 2-methylcyclohexane-1,3-dione in the presence of base. The Logic: Michael Addition:

An 8π electrocyclization followed by a 6π electrocyclization.

His thesis defense was in three days. His entire doctoral work—the synthesis of a complex alkaloid with potential neurogenerative properties—was sitting in a flask, looking nothing like the pristine white crystals he needed. Instead, it was a sludge-like, oily mess.
