Syntheses of the all-trans(E)-forms of the 6-methyl (7b), 7-methyl (7a), and 8-methyl (16) isomers of 13-phenyltrideca-4,6,8,10,12-pentaen-3-one are described. Comparison with asperenone, a pigment isolated from Aspergillus niger and A. awamori establishes structure (16) for the natural product.
13-苯基三苯甲基-4,6,8,10,12-的6-甲基(7b),7-甲基(7a)和8-甲基(16)异构体的全反式(E)形式的合成pentaen-3-one被描述。从黑曲霉和泡盛曲霉中分离出的色素天冬烯酮的比较建立了天然产物的结构(16)。
