Abstract

The cycloalkano-pyridines are prepared by reacting corresponding cycloalkano-pyridine-aldehydes with suitable organometallic compounds or Wittig or Grignard reagents or reacting compounds of the cycloalkano-pyridine alcohols type with suitable bromine compounds, and optionally varying the functional groups accordingly. The, cycloalkanopyridines are suitable as active compounds in medicaments, in particular in medicaments for the treatment of hyperlipoproteinaemia and arteriosclerosis.
