THE ANOMERIC EFFECT IN 1,3,5-TRITHIANE DERIVATIVES
Strong anomeric effect is observed in 1,3,5-trithiane derivatives. Phenylthio-axial conformation is found to be more stable than the equatorial in 2-phenylthio-1,3,5-trithiane in contrast to the fact that the anomeric effect is very small in 2-alkylthiothiane. 2-Benzoyloxy-1,3,5-trithane exists solely as the benzoyloxy-axial conformer.
