The conformation in 2H20 of 4-thio-L-lyxono-l,4-1actone (1) was studied by nuclear magnetic resonance spec~oscopy, by means of homonuclear (J]a,IH) and heteronuclear (Jl.,13c) coupling constants. The couplings were directly measured by a two-dimensional heteronucleus-coupled to~ hetero-half-filtered
The conformational difference of the title compound (1) in the solid state and in solution has been investigated by X-ray crystallography and high-field proton n.m.r. spectrometry. In the solid state, compound 1 adopts the "c,(D) conformation (la), whereas 1 exists preferentially in the 'C4(D) confo
