DEWAR1 has interpreted the chemistry of the mould metabolite, stipitatic acid, and of colchiceine (the methyl ether of which is the alkaloid colchicine) by postulating that they are derived from the hypothetical cycloheptatrienolone (I). This he termed 'tropolone', and he attributed to it quasi-aromatic character. This interesting suggestion, for which no tangible evidence was advanced2, has acquired more plausibility from the recent demonstration of Haworth, Moore and Pauson3 that purpurogallin is a trihydroxybenztropolone, as earlier suggested by Barltrop and Nicholson4, and from the finding of Erdtman and Gripenberg5 that the cedar-wood constituent γ-thujaplicin is an isopropyltropolone. Hitherto, a synthetic tropolone of established constitution has not been prepared, and the properties ascribed to such a structure have been based largely on speculation.
DEWAR1 通过假设拟环-七烯酮(I)是霉菌代谢物斯蒂皮酸和秋水仙碱(其甲基醚为生物碱秋水仙碱)的来源,解释了它们的化学特性。他称之为“特罗波烯”,并赋予其准芳香性。这一有趣的建议,虽然没有提出实际证据2,但因最近Haworth、Moore和Pauson3的研究表明紫褐酚是一种三羟基苯特罗波烯而获得了更多的可信度,早前Barltrop和Nicholson4也有类似的推测。此外,Erdtman和Gripenberg5发现的雪松木成分γ-桧木酚是一种异丙基特罗波烯。迄今为止,尚未制备出具有确定结构的合成特罗波烯,而归因于这种结构的性质主要是基于推测。
