Ns. Sarma et al., CRYSTAL AND MOLECULAR-STRUCTURE OF SCLEROPHYTIN-F METHYL-ETHER FROM THE SOFT CORAL CLADIELLA-KREMPFI, Journal of natural products, 56(11), 1993, pp. 1977-1980
A new cembranoid diterpene was isolated from the soft coral Cladiella
krempfi from Minicoy Island (India), and its structure was established
by X-ray crystallography to be sclerophytin F methyl ether [2] with t
he R absolute configuration at all six epimeric centers, assuming a co
nfiguration similar to that of sclerophytin C. Compound 2 may be an ar
tifact of the isolation process.
