Sphingosine occurrence

A sphingosine derivative, symbioramide (308), was obtained from the laboratory-cultured dinofagellate Symbiodinium sp. as a Ca2+-ATPase activator in the sarcoplasmic reticulum (250). The complete stereostructure of 308 was established by total synthesis (251). The occurrence of eo>f/iro-docosasphinga-4,8-dienine, as an ester (309), was found in Ammonia sulcata (252). This is the first example of a sphinga-4,8-dienine ester. A...
