RESUMO
In the title compound, C10H14Cl3NO5, the five-membered dioxolane ring adopts an envelope conformation. The C atom at the flap, which is bonded to the hy-droxy-methyl substituent, deviates from the mean plane of other ring atoms by 0.357â (5)â Å. There are two intra-molecular hydrogen bonds (O-Hâ¯N and N-Hâ¯O) between the hy-droxy and amino groups, so that O- and N-bound H atoms involved in these hydrogen bonds are each disordered with equal occupancies of 0.50. The methyl 2-methyl-prop-2-enoate substituent also shows a disordered structure over two sets of sites with refined occupancies of 0.482â (5) and 0.518â (5). In the crystal, mol-ecules are connected into a dimer by an O-Hâ¯O hydrogen bond. The dimers are further linked by N-Hâ¯O, C-Hâ¯N and C-Hâ¯O inter-actions, extending a sheet structure parallel to ([Formula: see text]01).
