A process for the manufacture of lavandulol and its esters, starting from the new compound 3,5,5-trimethyl-1,6-heptadien-3-ol, which is converted by conventional methods to 3,5,5-trimethyl-hepta-2,6-dien-1-ol or its esters, which are rearranged to lavandulol or lavandulyl esters by heating at from 150.degree. to 250.degree. C. Using the new process, the desirable product lavandulol, and its esters, which are also of great interest as scents, and even previously unknown lavandulyl esters, can be manufactured simply, in goods yields and in excellent purity, from easily obtainable starting compounds. Both the new starting compound 3,5,5-trimethyl-hepta-1,6-dien-3-ol and the new 3,5,5-trimethyl-hepta-2,6-dien-1-yl esters, obtained as intermediates, are scents and can be employed in the perfumery industry.
一种制备薰衣醇及其酯类的工艺,起始于新化合物3,5,5-三甲基-1,6-庚二烯-3-醇,通过常规方法转化为3,5,5-三甲基-庚-2,6-二烯-1-醇或其酯类,再通过在150℃至250℃加热重排制备薰衣醇或薰衣醇酯类。使用该新工艺,可以从易得到的起始化合物简单地、高产、高纯度地制备出理想的产品薰衣醇及其酯类,这些酯类也是非常有趣的香料,甚至包括以前未知的薰衣醇酯类。新的起始化合物3,5,5-三甲基-庚-1,6-二烯-3-醇和作为中间体获得的新的3,5,5-三甲基-庚-2,6-二烯-1-醇酯类都是香料,可以应用于香料工业。
