Rund 25 Hemiterpene 2 sind bekannt. Im Gegensatz zum synthetischen 2-Methyl1,3-butadien (Isopren) kommt 3-Methyl-2-buten-1-ol (Prenol) u.a. im Ylang-Ylangund Hopfenol naturlich vor. Isopentenylpyrophosphat ist die Biosynthese-Vorstufe der Terpene.

Monoterpenes and microbial metabolites in the soil
Environmental Pollution, 1990Volatile microbial metabolites were analysed in the soil beneath 15 H year-old Picea abies which had been fumigated for 5 consecutive years with charcoal-filtered air enriched with ozone and sulphur dioxide. Major compounds which could be attributed to the metabolism of basidiomycete fungi were oct-1-en-3-ol, oct-1-en-3-one and 1,3-octadiene. They were

Secondary Plant Substances. Monoterpenes
1976Monoterpenes occur in a variety of acyclic and cyclic structural types and derivatives (cf. Fig. 1), and represent one of the largest and most diverse families of natural products. The so-called isoprene rule was the first unified concept for a common structural relationship among terpenoid natural products (RUZICKA 1953).

Monoterpenes in breast cancer chemoprevention
Breast Cancer Research and Treatment, 1997A number of dietary monoterpenes have chemopreventive activity against rat mammary cancer. For example, d-limonene, which comprises over 90% of orange peel oil, has chemopreventive activity against rodent mammary cancer during the initiation phase as well as the promotion/progression phase.

Stereochemistry of Monoterpene Cyclization
1987The vast majority of the several hundred naturally occurring monoterpenes are cyclic and represent a relatively small number of skeletal themes multiplied by a very large range of simple derivatives, positional isomers and stereochemical variants.1 A unified conceptual framework for the origin of the various terpenoid types was put forward three ...
