Splitting up pyran rings |
| abstract |
ABSTRACT OF THE DISCLOSURE A chemical method for splitting the pyran ring of compounds such as 2,6,6-trimethyl-5,6-dihydro-4H--pyran is disclosed which consists in reacting the 4H-pyran derivatives concerned with water and a halo-gen-containing or hologen-donating catalyst at a comparatively low temperature, i.e. from 50°C to 130°C. Interesting results are obtained and a selection field is afforded as regards the products of the pyran-ring cleavage. |
