G. Jenner, EFFECT OF WATER ON CHEMO-SELECTIVITY AND ENDO-SELECTIVITY IN HIGH-PRESSURE DIELS-ALDER FURAN REACTIONS - HYDROPHOBIC OR POLAR EFFECTS, Tetrahedron letters, 35(8), 1994, pp. 1189-1192
Diels-Alder furan additions are less sensitive to pressure in aqueous
solution than in organic solvents. in some cases, water affects chemo-
and stereoselectivity. The interpretation lakes into account hydropho
bic as well as polar effects induced by water.
