摘要
以歧化松香中提取的去氢枞酸为原料,经酰化得到去氢枞酸酰氯。以松节油的主要成分α-蒎烯为原料,经过蒎酮酸、蒎酸、蒎酸二乙酯得到蒎酸二酰肼。蒎酸二酰肼与去氢枞酸酰氯在相转移催化剂的作用下反应,得到N,N′-二去氢枞基取代蒎酸二酰肼,再经三氯氧磷脱水环合,得到蒎酸二酰基双去氢枞基双噁二唑。初步探讨合成条件,通过元素分析、IR、MS、1H NMR和13C NMR对所合成的化合物进行了结构表征。
Dehydroabietic acid chloride was prepared from dehydroabietic acid which was isolated and purified from disproportionated rosin.Pinic acid dihydrazide was synthesized using α-pinene as raw material via pinonic acid,pinic acid and pinic acid diethyl esters.Pinic acid dihydrazide could readily react with dehydroabietic acid chloride under phase transfer catalysis to afford N,N′-didehydroabietyl pinic acid dihydrazide.Pinic acid diacyl-didehydroabietyl-bis-oxadiazole was synthesized by cyclization of N,N′-didehydroabietyl pinic acid dihydrazide with POCl3.The synthetic conditions were studied and the target compound was characterized by elemental analysis,IR,MS,1HNMR and 13CNMR.
