    • Although 1H NMR spectrum of an isomeric mixture (ca. 2:3) of the natural 3 is shown in Ref. 6, the cis-and trans-structures of the isomers are not assigned. The isomeric structures of the synthetic 3 and 9-11 were assigned by comparison to the 1H NMR data for the isomers of 7 and 8 having the similar characteristic tendency of the corresponding coupling constants and chemical shifts (Table 1). The precise conformations of these compounds are currently under consideration.
