Rhizochalin A, a Novel Two-Headed Sphingolipid from the Sponge Rhizochalina incrustata
摘要:
Rhizochalin A (4), the fourth representative of two-headed glycosphingolipids, was isolated as its peracetate from the sponge Rhizochalina incrustata. Its structure has been established as the 2-ethyl carbamoate of rhizochalin on the basis of spectroscopic data and chemical transformations.
