Webfirst cyclopentanoid natural product, i.e., hirsutic acid C (Figure 2, N54) in 1966, several cyclopentanoid natural products were isolated from a wide range of plant, microbi-al, and marine sources. Since then, synthesis of natural and non-natural products containing cyclopentane rings has become a vibrant area of chemical research. Hirsutic acid C WebJun 29, 2015 · Cyclopentanoid monoterpenes are known from plants and from defensive secretions of some insect species (orders Phasmatodea, Coleoptera, and Hymenoptera).
