Rearrangements of methyl 9β-hydroxy-11-oxo-(-)-kauran-19-oate to diterpene skeletons with new ring systems

Published

Journal Article

On treatment with boron trifluoride etherate-acetic anydride-acetic acid, the 9β-hydroxy-11-oxo derivative 1c of methyl(-)-kaur-9(11)-en-19-oate did not form a pinacolic type of rearrangement product (B-homo derivative), but instead it yielded compounds 2 and 3. With boron trifluoride etherate-acetic anhydride, however, compound 1c underwent a profound backbone rearrangement leading to the formation of compound 4a. © 1991.
