Novel ring expansion product of penicillin V β-sulphoxide: X-ray crystal structure of 3,8-dihydro-3,3,8,8-tetramethyl-6-phenoxyacetamido-1-oxo-oxazolo-[4,3-c][1,4]thiazinium chloride
Abstract
Pencillin V β-sulphoxide has been converted into a novel orange product which was structurally characterised as the 2H-1,4-thiazinium chloride (II) following an X-ray crystallographic study.
