The crystal structure of some 2-oxo-1,3,2-dioxathiolanes
Abstract
The trans diastereoisomers of 2-oxo-4(S)-phenyl-1,3,2-dioxathiolane and meso-2-oxo-4,5-diphenyl-1,3,2-dioxathiolane have been unambiguously identified by X-ray analysis; both adopt the half-chair conformation an differential endocyclic S–O bond lengths provide evidence for a stereoelectronic interaction with the SO group.
