New Nitrogen-Containing Labdanoids from Lambertianic Acid

摘要

Lambertianic acid (1) and some of its nitrogen-containing derivatives behave as promising psychotropic agents [1-3].We describe the synthesis of new diterpenoids of labdanum type containing the heterocyclic fragment of 10-oxa-3-azatricyclo[5.2.1.0]decene.
