Process for the enzymatic production of isomerically pure isosorbide-2 and 5-monoesters as well as their conversion into isosorbide- 2- and 5- nitrate

摘要

Process for the enzymatic production of isomerically pure compounds having the general formulae I and II ##STR1## in which the substituents R have the meanings stated in the claims, as well as their use for the production of isomerically pure isosorbide-2-nitrate having the formula V and isosorbide-5-nitrate having the formula VI, ##STR2## which are both important as therapeutic agents for coronary diseases.
