Loliolide - the most ubiquitous lactone

“…An important group among them are terpenoids (Grayson 1996, Grayson 1997, Grayson 2000, Molnár et al 2010, derived from terpenes. Terpenes are composed of interconnected isoprene particles (consisting of 5 carbon atoms) which results in the fact that these particles of terpenes are composed of 5, 10, 15, etc.…”

A Versatile Diquinane from Fulvene as a Building Block in Natural Product Synthesis II. A Facile Synthesis of Iridoids 10‐Deoxygeniposide, Mussaenoside, and 8‐epi‐Loganin

“…Iridoids comprise a large family of cyclopenta[c]pyran monoterpenes. 1 They are not only important for biosynthesis of some indole alkaloids but also have significant biological activities of their own. 2 In the synthesis of these compounds, construction of the cyclopentan[c]pyran ring system from a more stable cw-bicyclo[3.3.0]octene precursor in the final stage is an important strategy.…”

“…2 In the synthesis of these compounds, construction of the cyclopentan[c]pyran ring system from a more stable cw-bicyclo[3.3.0]octene precursor in the final stage is an important strategy. 3 In a previous paper, we have described an efficient synthesis of sarracenin (1) and loganin (2) starting from the versatile diquanane 3. 4 We now have used the intermediate 3 for the synthesis of 10-deoxy geniposide (4), 5 mussaenoside (5), 6 and 8-e/?/-loganin (6).…”

“…Iridoid monoterpenes, a class of cyclopentanoid natural products, are not only important for biosynthesis of some indole alkaloids but also have significant biological activities . These characteristics elicited widespread interest from synthetic chemists .…”
