Cw. Jefford et al., STRUCTURES AND ABSOLUTE-CONFIGURATIONS OF THE MARINE TOXINS, LATRUNCULIN-A AND LAULIMALIDE, Tetrahedron letters, 37(2), 1996, pp. 159-162
Latrunculin A (1) and laulimalide (2) were isolated from Fasciospongia
rimosa collected in Okinawan waters. By purification, single crystals
were obtained thereby enabling the absolute configurations of 1 and 2
to be determined by X-ray analysis.
