Phosphoric amides. Part 10. Base - promoted cyclization of phosphorotriamidates bearing the N-(2-chloroethyl) substituent, and the interconversion of cyclic products

Synthesis and Chemical Behavior of N-(2-Chloroethyl)O-alkyl-3-methyl-1,2-butadienephosphoniates

“…Keeping in mind the results of other authors, 10 we try to investigate the synthesized by us compounds 2d,e 11 in the reaction with some Downloaded by [Universite Laval] at 08:55 27 December 2014 strong bases such as buthyllithium. In this case, the cyclization between N-(2-chloroethyl)-and aryoxygroups at phosphorus took place, obtaining the compound 4 (Scheme 3).…”
