3,7-Bis(hydroxymethyl)benzoxepin-5(2H)-one (2) has been isolated from Marasmiellus ramealis cultures. Its structure was established by (a) spectrometry and (b) the synthesis of the corresponding 3,7-bis(methoxycarbonyl) compound (5), itself the product of mild oxidation of (2). The synthesis of (5) represents a new route to the benzoxepinone ring system.
3,7-双(羟甲基)苯并二恶唑-5(2 H)-一(2)已从Marasmiellus ramealis培养物中分离出来。它的结构是通过(a)光谱法和(b)相应的3,7-双(甲氧基羰基)化合物(5)的合成而确定的,该化合物本身是(2)轻度氧化的产物。(5)的合成代表了通往苯并异戊二烯环系统的新途径。
