摘要: 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 halogen-containing or halogen-donating catalyst at a comparatively low temperature, i.e. from 50.degree. C. to 130.degree. C. Interesting results are obtained and a selection field is afforded as regards the products of the pyran-ring cleavage.

摘要: A novel microporous resin which is useful in the treatment of hyperchloesterolemia. This resin is comprised of a cross-linked polystyrene matrix and is characterized by active moieties selected from among methylamino, methylammonium or a combination of methylamino and methylammonium groups. The porosity of this resin is capable of absorbing and retaining bile salts having an average diameter of 150-200 Angstrom units.
