tert-Butyl diethylphosphonoacetate Usage And Synthesis

Chemical Properties

Clear colorless liquid

Uses

tert-Butyl diethylphosphonoacetate is used as a reactant for preparation of hydroxymethylated dihydroxyvitamin D3 analogs via Wittig-Horner approach, as potential antitumor agents, synthesis of phosphopeptide mimetic prodrugs targeted to Src homology 2 (SH2) domain of signal transducer and activator of transcription 3 (Stat 3) and bicyclic triaminophosphine-promoted stereoselective synthesis of a,?-unsaturated esters, fluorides, and nitriles from aldehydes and ketones using Wadsworth-Emmons phosphonates

Synthesis

Triethyl phosphite (485 g) is warmed up to 90°C under N2 atmosphere in a three-necked round-bottomed flask, and /-butyl bromoacetate (541 g) is added dropwise into the system within 2 h. Then, the mixture is stirred at 90°C for around 4 hours and cooled to room temperature. The obtained mixture is distilled under vacuo to remove compounds with low boiling points, and the residue is collected as a colorless liquid tert-butyl diethylphosphonoacetate in 97 percent yield (680 g).
