Abstract

In methyl [5-methoxy-4-(4-methoxyphenyl) isochroman-3-yl]-acetate, C20H22O5, (I), and methyl [4-(2,5-dimethoxyphenyl)-8- methoxyisochroman-3-yl] acetate, C21H24O6, (II), the heterocyclic rings adopt half-chair conformations. The substituents at the 3- and 4-positions are in a trans configuration in both ( I) and ( II), being in an axial conformation in ( I) and in an equatorial conformation in ( ...
