Structure and absolute configuration of two new polybrominated C15 acetogenins from the sponge Mycale rotalis
Abstract
The structure and absolute configuration of two C15 polybrominated acetogenins 1 and 2, isolated from Mycale rotalis, have been determined by a combination of spectroscopic and X-ray diffraction analyses and through the chemical interconversion of 1 to 2; biosynthetic relationship between 1 and 2 is postulated.
