中文摘要 | A novel and versatile process was developed to prepare the trans-decalins Delta(9(11))-3 beta-acetoxysclareolide (2) and Delta(9(11)3)- acetoxy-8-epi-sclareolide (3), respectively, with 4a-methoxycarbonyl-2,7,7-trimethyl-1-oxo-cis-decalin-2-ene (4) and its C-3 hydroxyl derivative 5 from oleanolic acid (3 beta-hydroxyolean-12-en-28-oic acid, 1). Three key steps were (a) introduction of the AcO-12 group and the C-9, C-11 double bond at ring C of methyl 3 beta-acetoxyolean-12-en-28-oate (8) to afford the diene, methyl 3,12-diacetoxyolean-9(11), 12-dien-28-oate (11); (b) photolytic cleavage of the C-8, C-14 bond in the diene to give an acetoxy-substituted triene 14; and (c) oxidative cleavage of the triene or its hydrolyzed alpha,beta-unsaturated ketone product with m-CPBA/TsOH to give the cis- and trans-decalins 2-5.Delta(9(11))-3 beta-Acetoxysclareolide (2) was stereospecifically reduced to give 3 beta-acetoxy-9-epi-sclareolide (23), from which (-)- 9-epi-ambrox (7) was synthesized. |
