Some highly branched isoprenoid (HBI) alkenes are commonly used as proxies for palaeoceanographic reconstructions. However, there is a need to identify compounds that are sufficiently stable and abundant to be used as tracers of HBI oxidation in sediments. 2,6,10,14‐Tetramethyl‐7‐(3‐methylpent‐4‐enyl)‐pentadec‐5(Z/E )‐en‐4‐ols resulting from 2,6,10,14‐tetramethyl‐7‐(3‐methylpent‐4‐enyl)‐pentadec‐5‐ene
一些高支化异戊二烯(HBI)烯烃通常用作古海洋学重建的代理。然而,需要鉴定足够稳定和丰富以用作沉积物中HBI氧化示踪剂的化合物。由2,6,10,14-四甲基-7-生成的2,6,10,14-四甲基-7-(3-甲基戊-4-烯基)-十五烷基5(Z / E)-en-4-醇(3-甲基戊-4-烯基)-十五烷基5-烯似乎可用于此目的。
