G. Korengoldshlager et al., SINDUROL AND NEPHTHOSIDE - NEW TETRAPRENYLTOLUQUINOLS FROM THE SOFT CORAL SINULARIA-DURA AND NEPHTHEA SP, Journal of natural products, 59(3), 1996, pp. 262-266
Four new tetraprenyltoluquinoIs (2-5) have been isolated from the Indo
-Pacific soft, corals Sinularia dura and Nephthea sp. Sindurol (2), is
olated from the Sinularia, is a 1,3,5-trialkylated 2,8-dioxabicyclo[3.
2.1]octane, and nephthoside (4), obtained from the Nephthea, is a nerv
substituted hydroquinone D-arabinose glycoside. Compounds 3 and 5 are
closely related to nephthoside (4). The structure determination of al
l new compounds was based mainly on 1D- and 2D-NMR spectroscopy and ma
ss spectrometry, as well as some chemical transformations.
