Two synthetic methods leading to mono- or di-substituted 3-diethoxyphosphoryl-2,5-dihydro-2-furanones 8a - g are presented. Allylic bromination of the 2-diethoxyphosphoryl-2-alkenoates 6a - d and subsequent lactonization of the bromides 7a - d constitute the first method. The second method involves syn-hydroxylation of the 2-diethoxyphosphoryl-3-alkenoic acids 9a - c, e - g followed by lactonization and elimination of water from diols 10a - c, e - g. Syntheses of the starting 6a - d and 9a - c, g - e are also described.
