Two syntheses of deuterated gamma-lactones for use as internal standards in stable isotope dilution assays (SIDA) were developed. [2,2,3,3-2H4]-gamma-Octa-, -gamma-deca-, and -gamma-dodecalactones with >89% deuterium incorporation were prepared in 27, 17, and 19% overall yields, respectively, by the reduction of a doubly protected hydroxypropiolic acid with deuterium gas. [3,3,4-2H3]-gamma-Octa- and -gamma-dodecalactones were prepared in 6 and 23% yields with > 92% deuterium incorporation by the free radical addition of 2-iodoacetamide to [1,1,2-2H3]-1-hexene and [1,1,2-2H3]-1-decene, respectively. Reaction yields were highly dependent upon the purity of the 1-alkene starting material. The deuterated gamma-lactones were evaluated as internal standards for SIDA.
