Abstract

Arylidene dimalonate has the potential to serve as a bone-affinity agent in the treatment of bone disease, 1 and as the precursor for the synthesis of 3-Ar-glutaric acid. 2 Usually it is synthesized in two steps: the Knoevenagel condensation 3 of aromatic aldehydes with malonate or bromomalonate to form arylidene malonate followed by the Michael addition 4 of arylidene malonate with malonate to produce arylidene dimalonate. 5 Mori has reported a tandem Knoevenagel−Michael ...
