(-)-SCLAREOL CONVERSION IN RITTER'S REACTION CONDITIONS

Abstract

The main products of sclareol (1) Ritter’s reaction in mild conditions are (8R,13R)-Labd-14(15)-en-8,13-diacetamide (2) (8R,13S)-Labd-14(15)-en-8,13-diacetamide (3) stereoisomeric on C13 atom and having unrearranged native diol skeleton. We present in the current communication the results of sclareol converting (1) into nitrogen-containing labdanes in the Ritter’s reaction conditions
