Dibenzyl malonate was used in the preparation of tetraethyl 33-bis(benzyloxycarbonyl)propylene bisphosphonate.[3]It was also used in the preparation of benzyl umbelliferone-3-carboxylate via Knoevenagel condensation with 24-dihydroxybezaldehyde.

For R&D use onlynot for drug household or other uses.

Direct asymmetric reaction of dibenzyl malonate withN-tert-butoxycarbonyl aldimines in the presence of Yb(OTf)3and iPr-pybox (pybox pyridine bisoxazoline) complexes has been investigated.
