Abstract

2, 4-Bis(4-methoxyphenyl)-1, 3, 2, 4-di-thiaphosphetane-2, 4-disulfide (Lawesson's reagent, LR) reacted with certain bifunctional compounds, such as glycinamides 1, 1-glyceryl monoesters 4 and 3-mercapto-4-amino-5-substituted-1, 2, 4-triazoles 6 to yield five-membered phosphorus heterocycles 3,5, and 7, respectively. The cycloaddition reaction of LR with 1,3-butadiene 8 was investigated to form the six-membered heterocycle 9. The results of preliminary bioassays showed that these heterocycles obtained via cyclization reactions of LR possess significant selective herbicidal activity. The QSAR of 3 was also made. In conclusion, the cyclization reactions of LR with bifunctional substrates and 1,3-dienes afford novel routes to the syntheses ofbiologically active phosphorus heterocycles.
