Περίληψη:
Treatment of the secoiridoids oleuropein (4), ligstroside (5) and
methyloleoside (6) by beta -D-glucosidase in the presence of ammonium
chloride led exclusively to monomeric pyridine alkaloids 7, 1, and 8.
Dimeric 3,4,5-trisubstituted pyridines were obtained from methyloleoside
(6) when ammonium chloride was generated in the reaction mixture by
successive additions of ammonia and hydrochloric acid. The use of
ammonium acetate permitted conversion of secoiridoids 4 and 5 into the
naphthyridine alkaloid jasminine (3).
