Abstract
Two optically pure derivatives of α-cedrene — (1R,2R,5S,7R,8R)- 8-hydroxy-9-cedranone 2 and (lR,2R,5S,7R,8R,9S)-9-amino-8-hydroxycedrane 4 were prepared conveniently. An X-ray structural analysis of 2 was performed indicating that the hydroxycedranone exists as dimer due to one hydrogen bond in solid state.
