実験手順

Methyl vinyl ketone (90%, 185 ml, 2.0 mol) was added portionwise to a solution of methyl 3-mercaptopropionate (200 ml, 1.83 mol) and triethylamine (26 ml, 0.1 equiv) in THF (2.4 L). This mixture was heated slowly to 50 C and stirred at that temperature for 4.5 h. The solvent was then evaporated to afford 11 as an oil.
