BeschreibungSecurinine is derived from the leaf of Securinega suffruticosa Rehd., which was first separated by V.I.Murav’eva in 1956 . Securinega suffruticosa Rehd., a kind of subshrub plant, is widely distributed in temperate and subtropical regions . It has strong adaptability and can be planted in most parts of China. Moreover, it is rich in natural resources. Securinega suffruticosa Rehd. is a folk medicine whose root is the main component, with the effects of activating circulation, spleen, and stomach to treat rheumatism waist pain, limb numbness, infant malnutrition, and other diseases. The roots, stems, leaves, flowers, and skin of Securinega suffruticosa Rehd. contain alkaloids, in which securinine is the main ingredient.

HistorySecurinine was first isolated by a Soviet scholar from the Wusuli region, but its chemical structure was separated and finally determined by Chinese scholars from local sources . The main structural feature is a tetracyclic compound containing an indolizine, pyrrole elidine, or quinolizine ring and an α, β-unsaturated pentahydrin ring whose basic structural skeleton type is as shown in what follows .Owing to the complexity of the chemical reaction of securinine, reports on its chemical reactivity and structural modification have been relatively scarce since securinine was reported on in 1956. However, the research on chemical total synthesis and biological activities of securinine has made a certain amount of progress.Securinine has a rigid molecular structure containing four rings and three chiral centers, which makes synthesis difficult. From 1974 to 1978, three research groups from Japan, the USA, and Canada studied the biosynthesis of securinine by feeding animals with isotope-labeled S. suffruticosa.

Verwenden3,4-Dinitrochlorobenzene is a useful reactant in organic synthesis.
