摘要：
Irradiation of the nor-diterpene atractyligenin at lambda = 254 mn in methanol gave, on one hand, the decarboxylation product, and provided, on the other hand, the transformation of the C-20 angular methyl into a methylene-carbomethoxy group. A photochemical pathway involving formation of C-19/C-20 bond is suggested. (C) 2001 Elsevier Science Ltd. All rights reserved.
