The transformation of the isopimaric system 1 into the sandaracopimaric system 2 is described.Photooxygenation of 1a led selectively to the formation of 3β-acetoxysandaracopimaradien-7α-ol (3a) whose acetylation and subsequent lithium-ammonia reduction led to the alcohol 2c.The sandaracopimaric system 2 was also obtained by reduction of the 3β-acetoxy-6,7-dehydrosandaracopimarene 5.
