摘要
The axinellid sponge Acanthella carteri Dendy, 1889 (= Acanthella aurantiaca Keller, 1889) from the Hanish Islands, Yemen, on EtOH extraction followed by FC and HPLC purification gave the first example of branched glycerol enol ether, hanishenol B (3) alongside a major unbranched analogue, hanishenol A (1). Their structures were elucidated from NMR and MS spectra and through the ozonolysis product of 1, while the absolute configuration was assigned from exciton coupling with the dibenzoate derivative 2.
