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