Acid catalyzed cyclization of Diels-Alder adducts of myrcene of formula 3 is performed in the presence of hydroxyl-containing compounds, giving the resulting mixtures of isomeric acyloctahydronaphthalenes of formulas 1 and 2 enhanced quantities of isomers that are particularly useful in perfumery because of their woody-amber odors with, enhanced amber note. Formulas 1,2 and 3 are as follows:
R1, R2, R3 and the wavy lines have the meanings given herein.
在含羟基化合物存在的情况下,对式 3 的月桂烯的 Diels-Alder 加合物进行酸催化环化,得到式 1 和 2 的酰基八氢萘异构体混合物,这种混合物中的异构体数量增加,在香水中特别有用,因为它们具有木香和琥珀香味。配方 1、2 和 3 如下:
R1、R2、R3 和波浪线的含义如本文所述。
