3-(4,8,12-Trimethyltridecyl)furan (I) was isolated from cigarette smoke condensate and its structure was confirmed by synthesis. During attempts at synthesis, two general routes to 3-substituted furans were investigated. In the first, greatly improved procedures for the preparation of 3-furoic acid were devised; the second involved thermal cyclisation and dehydration of 1,2,3,4-tetraols.
从香烟烟雾冷凝物中分离出3-(4,8,12-三甲基十三烷基)呋喃(I),并通过合成确认了其结构。在尝试合成过程中,研究了两条通向3取代呋喃的一般路线。首先,设计了大大改进的制备3-糠酸的方法。第二个涉及1,2,3,4-四元醇的热环化和脱水。
