Trimethyl-2,6,10-dodecatrien

Farnesol (3,7,11 -trimethyl-2,6,10-dodecatrien-l-ol) (181) is the sesquiterpene analogue of geraniol (20) and nerol (14), depending on its 2E- resp. 2Z-configuration. It is a component of many blossom oils. It is a colourless liquid with a linden blossom odour, which becomes more intense when evaporated, possibly due to oxidation [26]. The levels found in essential oils are generally low (0.5-1.0%) with the exception of cabreuva, which contains up to 2.5% farnesol, and the distillate from flowers of Oxystigma buccholtzii Harms., which contains up to 18% farnesol [27].

A solution of 45 mmols of 1-bromo-3,7,11-trimethyl-2,6,10-dodecatriene (obtained from synthetic farnesol, commercially available and containing four isomers) in 10 ml of benzene was added dropwise at 0°C to a stirred solution of 45 mmols of piperonyipiperazine in 60 ml of benzene containing 5 g of triethylamine. The mixture was stirred for 2 hours and then the precipitated triethylammonium bromide was filtered off. The benzene solution was washed first with water and then with K2CO3 solution and finally dried (K2CO3). Removal of ben-...

Eurthermore, elastomeric PUs with flexible degradability were prepared with PCL, HDI, and varying chain extenders [46,47]. Specifically, three new PUs, PU-S, PU-M, and PU-F, with bioactive isosorbidediol (l,4 3,6-dianhydro-D-sorbitol) (ISO), bis(2-mercaptoethyl) ether, and ISO combined with 3,7,1 l-trimethyl-2,6,10-dodecatrien-l-diaminobutane amide (TDD), respectively, used as chain extenders were synthesized [46,47]. These chain extenders acted as labile units and introduced different levels of polymer chain mobility into the polymeric materials [46].
