D. Sikora et T. Gajda, A CONVENIENT SYNTHESIS OF 5-SUBSTITUTED 1-[1-(DIETHOXYPHOSPHORYL)ALKYL]-1H-1,2,3-TRIAZOLES, Synthetic communications, 28(7), 1998, pp. 1215-1222
5-Substituted 1-[1(diethoxyphosphoryl)alkyl]-1H-1,2,3-triazoles were p
repared in good yields (61-83%) via thermal 1,3-dipolar cycloaddition
of diethyl 1-azidoalkylphosphonates and 2-oxoalkylidene triphenylphosp
horanes.
