(3-Azido-1-alkenyl)phosphonates 8 with R1 = H are prepared regioselectively by reaction of secondary (1-hydroxy-2-alkenyl)phosphonates 3 with TPP/DEAD/HN3 and subsequent thermal 1,3-rearrangement of the allylic α-azidophosphonates 5 primarily f
Reaction of Dialkyl Phosphites with α-Enones. I. - Synthesis and Allylic Rearrangement of Dimethyl (1-Hydroxy-2-alkenyl)- and (1-Hydroxy-2-cycloalkenyl)phosphonates
