Abstract
A simple synthetic derivative of natural diterpene cembrene [(1S,2E,4S,7E,11E)-4-morpholin-4-ylcembra-2,7,11-trien-5-one E-oxime] was found to be highly sensitive to acids (sulfuric and trifluoroacetic), and it is transformed under acidic conditions to atricyclic bridged system with the 5,6-dihydro-4H-1,2-oxazine moiety.
