title: Studies on the intramolecular C[bond]H...X (X = O, S) interactions in (S)-N-acyl- 4-isopropyl-1,3-thiazolidine-2-thiones and related 1,3-oxazolidin-2-ones.
abstract: [reaction: see text] Two intramolecular C[bond]H...X (X = O, S) interactions in (S)-N-acyl-4-isopropyl-1,3-thiazolidine-2-thiones are documented through crystallographic and spectroscopic evidence and high-level theoretical calculations. The key role played by the sulfur atoms has been made clear by comparison with structurally related (S)-N-acyl-4-isopropyl-1,3-oxazolidin-2-ones.
