Abstract :
The title compounds, C21H22N2O2S (I) and C18H15N3O4S (II), are structural analogs of the alkaloid Thiosporine B. Both molecules adopt a near-planar V-shaped conformation, which is consolidated by intramolecular N—H⋯N and C—H⋯O hydrogen bonds. The crystal structure of (I) consists of mlecular stacks along the a axis, in which the molecules are linked to each other by π(S)⋯π(C) interactions. In the crystal of (II), molecules are linked into chains by C—H⋯O hydrogen bonds and the chains are cross-linked into (100) sheets by π–π stacking interactions.
