Methyl 3-dehydroxy-3-oxoursolate
Four of the five six-membered rings of the title penta-cylic triterpene, C(31)H(48)O(3), adopt chair conformations; the fifth, which has a C=C double bond, adopts an approximate envelope conformation.

Four of the five six-membered rings of the title penta-cyclic triterpene, C(33)H(52)O(4), adopt chair conformations; the fifth, which has a C=C double bond, adopts an approximate envelope conformation.
متن کاملMethyl 3-(3-pyridylmethylene)carbazate
In the crystal of the title compound, C(8)H(9)N(3)O(2), mol-ecules are linked by N-H⋯N hydrogen bonds, forming S(7) chains propagating in [010].
متن کاملMethyl 3-(3-benzoylthioureido)propanoate
In the title compound, C(12)H(14)N(2)O(3)S, the propyl acetate group and the benzoyl group adopt a cis-trans conformation, respectively, with respect to the thiono S atom across the C-N bonds. The phenyl ring is twisted relative to the the thio-urea mean plane, forming a dihedral angle of 24.16 (9)°. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal packing is stabilized by inter-molec...
متن کامل(E)-Methyl 3-{3-[(4-bromophenoxy)methyl]phenyl}acrylate
In the mol-ecule of the title compound, C(17)H(15)BrO(3), the rings make a dihedral angle of 75.54 (17)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, and the π-stacked dimers inter-act with neighbouring dimers via C-H⋯π stacking inter-actions.
