2-[1-(2-Hy­droxy-4-meth­oxy­phen­yl)ethyl­idene]-N-methyl­hydrazinecarbo­thio­amide

In the title compound, C₁₁H₁₅N₃O₂S, the dihedral angle between the mean planes of the benzene ring and hydrazinecarbo­thio­amide group is 9.2 (1)°. An intra­molecular O—H...N hydrogen bond is observed, serving to maintain an approximately planar conformation for the molecule. In the crystal, inversion dimers linked by C—H...O inter­actions occur. Further C—H...O contacts link dimers into (010) chains.

Bruceolline J: 2-hy­droxy-3,3-dimethyl-2,3-di­hydro­cyclo­penta­[b]indol-1(4H)-one

The 12-membered cyclo­penta­[b]indole ring system in the title compound, C₁₃H₁₃NO₂, deviates only slightly from planarity (r.m.s. deviation = 0.051 Å). In the crystal, N—H...O and O—H...O hydrogen bonds link the mol­ecules into sheets parallel to (100). The five-membered cyclopentanone ring is in slightly distorted envelope conformation with the C atom bearing the hydroxy substituent as the flap.
