The pigments responsible for the blue colour of the North American polypore Albatrellus flettii have been isolated and their structures elucidated by spectroscopic methods. Albatrellin, a dimeric meroterpenoid with a furylbenzoquinone chromophore, is accompanied by its 16-hydroxy and 16-oxo derivatives. The latter has recently been described as grifolone B from a Japanese collection of A. caeruleoporus
北美多孔信天翁的蓝色色素已被分离出来,并通过光谱方法阐明了它们的结构。Albatrellin 是一种具有呋喃基苯醌发色团的二聚体类萜,伴随着其 16-羟基和 16-氧代衍生物。后者最近被描述为来自日本 A. caeruleoporus 的 grifolone B。基于 albatrellin 是通过 grifolinquinone 与呋喃衍生物 cristatin 的氧化偶联在自然界中形成的想法,在体外合成了蓝色颜料。该反应可用于合成多种类似物。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
