The regioselective course of the Diels-Alder reaction in supercritical carbon dioxide was investigated. The analysis failed to confirm the previously reported dramatic effect of reaction conditions on Diels-Alder regiochemistry. The results highlighted the importance of verifying phase behavior when sampling CO2 reaction mixtures and the utility of a view-cell reactor that allows direct monitoring of phase behavior (Ren-slo et al., 1997).

Diels-Alder reaction of methyl vinyl ketone (MVK) with iso-prene, the adduct is obtained in 91% yield in the presence of 10 mol % Sc(OTf)3, while 10 mol % Y(OTf)3 or Yb(OTf)3 gives only a trace amount of the adduct.Sc(OXf)3-catalyzed Diels-Alder reactions generally provide high yields with high endo selectivities. The present Diels-Alder reaction even proceeds in aqueous media. Thus, naphthoquinone reacts with cyclopenta-diene in H2O-THF (9 1) at room temperature to give the corresponding adduct in high yield (100% endo) (eq 16). Sc(OTf)3 also serves as an effective catalyst for Diels-Alder reactions in supercritical carbon dioxide (sc C02). ... [Pg.391]
