2 (3×10 mL). The resin was dried at 70°C under reduced pressure for at least 2 h. The increase in weight of the resin was a measure of the amount of cycloadduct formed on the resin. The use of high pressure was prefered over refluxing in toluene in view of shorter reaction times and higher yields. 4-Methoxybenzyl (E/Z)-2-nitro-3-phenyl-2-propenoate reacted with 2,3-dimethylbutadiene in refluxing toluene for 48 h yielding 73% of cycloadduct; at 15 kbar and room temperature (18 h) the yield was 91%.
