Synthesis of New Phosphonate Derivatives of Naphtho[2,1-b[Pyran]3,2-e][1,2,4]Triazolo [1,5-c]Pyrimidines
摘要：
The synthesis of new naphthopyranotriazolopyrimidines phosphonates 4ai in good yields (74%93%) has been accomplished via MichaelisArbusov rearrangement by the reaction of trialkyl phosphite with naphthopyranotriazolopyrimidines chloride 3ae, which were obtained from ±-functionalized iminoethers 1 in two steps. The synthesized compounds 4ai were completely characterized by IR, 1H, 13C, and 31P NMR and HRMS.
