Abstract

Using 0.1 mol% to 1 mol% potassium carbonate in an acetonitrile–deuterium oxide mixture acts as a ‘privileged’ reaction system, which at ambient temperature affords, via a one-pot–one-cycle procedure, α-D-diazoacetates, α-D-diazoacetamides, or α-D-diazoketones from the corresponding nondeuterated form. The protocol is inexpensive, employs readily available materials, does not require harsh reaction conditions, requires two hours for completion, and affords the desired products in good yields and with excellent levels of deuterium incorporation. Exemplifying our protocol the first isotope labelled synthesis of N-Boc-α-D-azaserine with ≥95% D-incorporation is reported.

  • 25 We were concerned that MeOH may not be compatible with sensitive substrates such as 24. That acetone and a weak base may generate aldol byproducts and that DMSO and DMF may be difficult to efficiently remove from the sensitive α-D-diazo products
  • 26 We used Romil UpS Ultra gradient MeCN (Code H050) that contained <0.0025% H2O. Throughout the study the ratio of MeCN–D2O was kept constant, i.e. 1.17:1 (v/v). Furthermore relative to the starting material, diazoacetate, the number of equivalents of MeCN and D2O was kept at 41:100 respectively unless otherwise indicated
