| l,3-Di-terf-butyl-6//-benzo[b]naphtho[l,2-d]pyran-6-thione, a Severely Helically Distorted Thionolactone-Bridged Biaryl  | | | | Abstract
| The title compound 2c, a potentially useful synthetic intermediate in stereoselective biaryl synthesis, has been prepared from the oxolactone lc, by treatment with Lawesson's reagent. An X-ray structure analysis reveals its strongly helically distorted structure, the overall molecular distortion even slightly exceeding that of the corresponding oxo compound lc. | | | |
