%X The soft coral Sinularia polydactyla has yielded six highly functionalized diterpenes. The known diterpenes pukalide (2) and 1-epithunbergol (3) were readily identified by spectral comparison with authentic samples. The new natural products 13 &#945;-acetoxy-11&#946;, 12&#946;-epoxypukalide (4),13 &#945;-acetoxypukalide (5) and its allylically rearranged isomer (6) were identified on the basis of 2D-n.m.r. experiments at 300 MHz and by spectral comparison with the known compounds pukalide (21, lophotoxin (8) and epoxypukalide (9). A minor, relatively unstable metabolite (7) is tentatively identified as a 3,4:5,6-bisepoxy derivative of (6). The biological implications of these findings are discussed.
