Synthesis of New Aminophosphonothiophene Derivatives
摘要:
The reaction of gamma,gamma'-diphosphonylketones 1 with active methylenenitriles and sulfur in basic conditions led to the new 5-amino-2(phosphonomethyl)-3-(phosphonoethyl)thiophenes 2. These compounds were then used in the Horner-Wadsworth-Emmons reaction to give 5-amino-2-alkenyl-3-(phosphonoethyl)thiophenes 3. The structure of all obtained products was confirmed by NMR (H-1, P-31 C-13) and IR spectroscopy.
