Pterogorgia citrina

Fiirstner and co-workers relied on a three-component Knochel-type [67] coupling to achieve the synthesis of (+)-dehydrohomoancepsenolide 136 (Scheme 12.21) [68], a secondary metabolite isolated from the gorgonian octocoral Pterogorgia citrina collected off the west coast of Puerto Rico [69]. 

Trivial names in this series are misleading. Numbering systems vary. Constit. of the gorgonian Pterogorgia citrina. Solid. Mp 99.6-101.6°. [a] -M6.7 (c, 2 in CHCI3).
