Abstract
Electrochemical deoxygenation of methyl 7βketoβlithocholate using deuterated reagents, followed by base hydrolysis is shown to give [7,7β^2^H~2~] lithocholic acid in 60% overall yield and 86% ^2^H~2~ isotopic purity.

## Abstract Dimethyl (7β^2^H~3~ 2βoxoheptyl) phosphonate 4 has been prepared from ^2^H~3~ methyl iodide. The phosphonate should be a useful reagent for the synthesis of deuterium labelled prostaglandins and thromboxanes.
