“…80 A large number of phlorobenzophenones and phlorohydroxybenzophenones have been reported to occur in nature. Phlorobenzophenones such as cotoin (52, from Aniba duckei [81][82][83] and Nectandra coto 84 ) isocotoin (53), hydrocotoin (54, from Aniba pseudocoto) 81 and methyl hydrocotoin (55, from Aniba pseudocoto 81 and Cascara sagrada 85 ), and the structurally related compounds 56 and 57 have been isolated from Leptospermum luehmannii. 83,86 Another phlorobenzophenone analogue, paglucinol (58), in which a 3-isopropenyl-1,1-dimethylcyclopentane moiety is linked to the phloroglucinol nucleus, was isolated from a cell suspension culture of Hypericum patulum.…”
