Technical Abstract: Lesquerella (Lesquerella fendleri) is a crop grown in the southwestern U.S. and has proven to be a useful U.S.-based source of hydroxy fatty acid (HFA). The lesquerella seed is high in oil content (~30%), of which the principal component of lesquerella oil is lesquerolic acid (55%), a C20 HFA. Lesquerolic acid is a potential domestic alternative to castor oil’s ricinoleic acid, a C18 HFA, which is not produced in the U.S. due to toxic properties of the castor bean. It has also been shown that phosphonates and their corresponding phosphonic acids are functional moieties that display a wide variety of biological and synthetic applications. In particular, bisphosphonates have found wide use as osteoporosis therapeutics as they bind Ca2+ and are known to increase bone density. We are interested in combining these two characteristics—naturally-occurring HFAs modified to produce bisphosphonates and their corresponding phosphonic acids—to produce a novel family of phosphorus-containing lesquerolic and ricinoleic acid derivatives. The results of these syntheses will be presented.
