| DIBENZYL MALONATE Usage And Synthesis |
| Chemical Properties | CLEAR YELLOWISH LIQUID | | Uses | Dibenzyl malonate was used in the preparation of tetraethyl 3,3-bis(benzyloxycarbonyl)propylene bisphosphonate. It was also used in the preparation of benzyl umbelliferone-3-carboxylate via Knoevenagel condensation with 2,4-dihydroxybezaldehyde. | | General Description | Direct asymmetric reaction of dibenzyl malonate with N-tert-butoxycarbonyl aldimines in the presence of Yb(OTf)3 and iPr-pybox (pybox = pyridine bisoxazoline) complexes has been investigated. | | Purification Methods | Dissolve the ester in toluene, wash it with aqueous NaHCO3, H2O, dry over MgSO4, filter, evaporate and distil it at high vacuum.
